Verified Answer
Three coins are tossed simultaneously. Find the probability of getting...
Given:
Three coins are tossed simultaneously.
Formula:
Probability = Number of favorable outcomes/ Total number of outcomes.
Calculation:
When three coins are tossed then the outcome will be any one of these combinations. (TTT, THT, TTH, THH. HTT, HHT, HTH, HHH).
So, the total number of outcomes is 8.
Now, for exactly two heads, the favorable outcome is (THH, HHT, HTH).
We can say that the total number of favorable outcomes is 3.
Again, from the formula
Probability = Number of favorable outcomes/Total number of outcomes
Probability = 3/8
 The probability of getting exactly two heads is 3/8.
