Question

Three coins are tossed simultaneously.
Condition for event A : To get at least two heads.
Condition for event B : To get no head.
Condition for event C: To get head on the second coin.​

Answer 1

Answer:

n(S)=2×2×2=8

n(A)=HHT,HTH,THH,HHH=4,

n(B)=TTT=1  

n(C)=THT,HHH,HHT,THH=4  

Q and R and P and Q are nutually exclusive as they have nothing in their intersection.

Answer 2

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

N (S) = 8

Event A = { HTH,HHT,HHH,THH }

N (A)= 4

Event B = {TTT}

N (B) = 1

Event C = {THT , HHH , HHT , THH }

N (C) =4
