Question

three coins are tossed simultaneously. list the sample space for event . find the probability of 2 heads

Answer 1

Answer:

Sample space =

(HHH, TTT, HHT, HTH, THH, TTH, THT, HTT)

So sample space is 8

Here number of two heads is 3

So probability of exactly 2 heads is 3/8

If my answer satisfies you then give me thanks.

Answer 2

Answer:

Probability of 2 heads = 2/6 = 1/3

Step-by-step explanation:

(Don't confuse this with set theory)

Total number of possibilities = 6 (one head and one tail from each coin)

Required possibilities = 2 (two heads)

Probability = 2/6 = 1/3
