Question

If 3 coins are tossed what is probability of at most two heads

Answer 1

how many times the coin was tossed

Answer 2

Answer:

p(e)=7/8

Step-by-step explanation:

total outcomes=8

(H,H,H), (T,T,T)

(H,H,T), (T,T,H)

(H,T,H); (T,H,T)

(H,T,T); (T,H,H)

Favourable outcomes= (T,T,T)

(H,H,T), (T,T,H)

(H,T,H); (T,H,T)

(H,T,T); (T,H,H)

p(e)=7/8
