Question

Solve this:

60. An experiment consist of flipping a coin and then flapping it a second time if head occurs. If a tail occurs on the first flip, then a six-faced die is tossed once. Assuming that the outcomes are equally likely, what is the probability of getting one head one tail?


(a) 1/4 (b) 1/36
(c) 1/6 (d) 1/8

Answer 1

on fliping the coin there is two chances either come head or come tell .
i.e { H, T }
on fliping two coin s
ample space will be S(E)= {HT, TH, HH,TT}
S(P)=from of the condition occur from sample space
so probability P(E)= $\frac{S\left(E\right)}{S\left(P\right)}$=$\frac{1}{4}$
