Question

IN TOSSING OF 3 COINS THE PROBABILTIY OF GETTING EXACTLY 1 HEAD IS..........???? CORRECT ANSWER ="BRAINLIST" SPAMING="REPORTED"​

Answer 1

The number of outcomes from tossing three coins is 8 (HHH,HHT,HTH,HTT,THH,THT,TTH and TTT). Of these outcomes, three qualify as having only one head, HTT,THT and TTH. Therefore the probability of getting exactly 1 head when three coins are tossed (simultaneously or not) is 3/8.

Answer 2

Step by step workout

step 1 Find the total possible combinations of sample space S

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

S = 8

step 2 Find the expected or successful events A

A = {HTT, THT, TTH}

A = 3

step 3 Find the probability

P(A) = Successful Events

Total Events of Sample Space

= 3

8

= 0.38

P(A) = 0.38

0.38 is the probability of getting exactly 1 Head in 3 tosses.
