If you flip the five coins, and the probability of one coin being "tails" is 0.50, what is the probability of getting "tails" on
jenyasd209 [6]

Answer: 0.03125

Step-by-step explanation:

We know that the probability of getting a tail , we toss a fair coin = 0.5

Given : Total number of trials = 5

Using binomial probability formula :

P(x)=^nC_xp^x(1-p)^{n-x}, where P(x) is the probability of getting success in x trails, n is total number of trials and p is the probability of getting success in each trial.

The probability of getting "tails" on all five coins :_

P(x=5)=^5C_5(0.5)^5(1-0.5)^0=(1)(0.5)^5=0.03125

Hence,  the probability of getting "tails" on all five coins =0.03125
