Question

Three coins are tossed simultaneously 150 times with the following frequencies of different outcomes. compute the probability of getting atleast two tails

Answer 1

Answer:

s={HHH, HHT, THH, HTH, TTT, TTH, THT, HTT} n(S) ={8}

LET THE EVENT A BE THE THE PROBABILITY OF GETTING ATLEAST TWO TAILS

A={TTT, TTH, THT, HTT}

n(A) ={4}

P(A) =n(A) /n(S)

P(A)=4/8

P(A) =1/2

I hope you this will help you because I don't know about 150 times
