RS Aggarwal Test: Probability - Question 1

### Which of the following cannot be the probability of an event?

Detailed Solution for RS Aggarwal Test: Probability - Question 1

To determine which of the following cannot be a probability:

- A: 1/3 is a valid probability as it falls between 0 and 1.
- B: 0.1 is also a valid probability, representing 10% likelihood.
- C: 3% can be converted to a decimal (0.03), making it a valid probability.
- D: 17/16 is greater than 1, violating the probability rule (must be between 0 and 1).

Therefore, D: 17/16 cannot be the probability of an event.

RS Aggarwal Test: Probability - Question 2

### A card is drawn from a deck of 52 cards. The event E is that card is not an ace of hearts. The number of outcomes favourable to E is

Detailed Solution for RS Aggarwal Test: Probability - Question 2

Total number of outcomes =52

we have only 1 ace of hearts , so the number of favourable outcomes of E ,

where E is card not an ace of hearts = 51.

Probability facts.

RS Aggarwal Test: Probability - Question 5

If P(A) denotes the probability of an event A, then

RS Aggarwal Test: Probability - Question 6

When a die is thrown once, the probability of getting an odd number less than 3 is

Detailed Solution for RS Aggarwal Test: Probability - Question 6

odd number less than 3 is only 1
so probability=1/6

RS Aggarwal Test: Probability - Question 7

The probability of getting a bad egg in a lot of 400 is 0.035. The number of bad eggs in the lot is

Detailed Solution for RS Aggarwal Test: Probability - Question 7

It is given that

Total number of eggs = 400

Probability of getting a bad egg P(E) = 0.035

Consider x as the number of bad eggs

The formula to find the probability is

P(E) = Number of bad eggs/ Total number of eggs

Substituting the values

0.035 = x/400

By further calculation

35/1000 = x/400

x = 35/1000 x 400

x = 140/10

x = 14

Therefore, the number of bad eggs in the lot is 14.

RS Aggarwal Test: Probability - Question 8

A coin is tossed 1000 times and 640 times a ‘head’ occurs. The  probability of occurrence of a head in this case is

Detailed Solution for RS Aggarwal Test: Probability - Question 8

P = 640/1000 = 0.64

RS Aggarwal Test: Probability - Question 9

Two coins are tossed simultaneously. The probability of getting atmost one head is

Detailed Solution for RS Aggarwal Test: Probability - Question 9

Two coin tossed
Total sample space = {HH, HT, TH, TT}
Sample space for getting atmost one head = {TT, TH, HT}
P(s) = 3/4
