Two coins are tossed simultaneously 300 times. Either one or two heads...
Out of 300 times 198 times head has come.
Therefore
the probability of getting no head is
300-198=102
102/300=0.34
Therefore
the probability of getting no head is
300-198=102
102/300=0.34

Two coins are tossed simultaneously 300 times. Either one or two heads...
To solve this problem, we need to use the concept of probability. The probability of an event occurring is defined as the number of favorable outcomes divided by the total number of possible outcomes.
Let's break down the given information and solve the problem step by step.
Given:
- Two coins are tossed simultaneously 300 times.
- Either one or two heads are obtained 198 times.
Step 1: Determine the total number of possible outcomes.
When two coins are tossed simultaneously, there are 2 possible outcomes for each coin: either a head (H) or a tail (T). Since there are two coins, the total number of possible outcomes is 2 * 2 = 4.
Step 2: Determine the number of favorable outcomes.
The problem states that either one or two heads are obtained 198 times. This means that the number of favorable outcomes is 198.
Step 3: Calculate the probability of getting no head.
To find the probability of getting no head, we need to subtract the number of favorable outcomes from the total number of possible outcomes and divide it by the total number of possible outcomes.
Number of favorable outcomes = Total number of possible outcomes - Number of favorable outcomes
Number of favorable outcomes = 300 - 198
Number of favorable outcomes = 102
Probability of getting no head = Number of favorable outcomes / Total number of possible outcomes
Probability of getting no head = 102 / 300
Probability of getting no head ≈ 0.34
Therefore, the correct answer is option 'D' - 0.34.
In summary:
- The total number of possible outcomes when two coins are tossed simultaneously is 4.
- The number of favorable outcomes, where either one or two heads are obtained, is 198.
- The probability of getting no head is calculated by subtracting the number of favorable outcomes from the total number of possible outcomes and dividing it by the total number of possible outcomes.
- The probability of getting no head is approximately 0.34.

To find the probability of getting no head, we need to subtract the number of favorable outcomes from the total number of possible outcomes and divide it by the total number of possible outcomes.
Number of favorable outcomes = Total number of possible outcomes - Number of favorable outcomes
Number of favorable outcomes = 300 - 198
Number of favorable outcomes = 102
Probability of getting no head = Number of favorable outcomes / Total number of possible outcomes
Probability of getting no head = 102 / 300
Probability of getting no head ≈ 0.34
Therefore, the correct answer is option 'D' - 0.34.
