Question

Three coins are tossed simultaneously. Find the probability of getting two heads.

Answer 1

if three coins r toseed simultaneously.Let S be te sample space. Let h represents heads nd T represents tail.

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

n (S)= 8

Event A: getting two heads

A={HTH HHT THH}

n (A)=3

p (A)= n (A)/n (S)=8/3

the probability of getting 2 heads is 8/3

Answer 2

Please mark me as the Brainliest❤

Total number of outcomes = 8

Sample space = (HHH) (TTT) (HTT)

(TTH) (HTH) (THT)

(HHT) (THH)

P(of getting two heads ) = 3/8
