Question

three different coins are tossed simultaneously find the probability of getting exactly one head

Answer 1

Answer:1/3

Step-by-step explanation:

p(e)=no.ofpossible trails/total no. of trails

Answer 2

sample space of three coins

S = {HHH , HHT , HTH, THH, TTT, TTH , THT, HTT }

n (S) = 6

let the event A be the that getting exactly one head .....

A = { TTH , THT , HTT }

n (A) = 3

p(A) = n(A) / n(S)

= 3 / 6

2

probability = 2
