Given:
There are 3 fair coins.
Formula Used:
Probability of occurrence of an event = P(E) = Number of favorable outcomes/Number of possible outcomes = n(E)/n(S)
Calculation:
We know that:
When three fair coins are tossed simultaneously,
The numbers of possible outcomes are n(S)
n(S) = 23 = 8 = {HHH, HHT, HTH, THH, TTT, TTH, THT, HTT}
The number of favourable outcomes is
n(E) = {HTT, THT, TTH} = 3
Probability = 3/8
∴ The probability of getting one head = 3/8.
