Question

a coin is tossed 200 times and is found that a tail comes up for 120 times find the probability of getting a tail

Answer 1

coin is tossed 200 times therefore we will have 200 results
.let 'S' be the sample space
.:n(S)=200

let 'A' be the number of times we get a tail
.:n(A)=120

.:P(A)=n(A)/n(S)
=120/200
=12/20
=6/10 = 60%

.:P(A)=60%

ANSWER
Possibility of getting a tail is 60%

Answer 2

COIN TOSSED = 200 TIMES
TALES COME = 120
SO THE PROBABILITY OF TAIL IS =

THE NUMBER OF OUTCOMES TAIL /TOTAL NUMBER OF TRIALS

120/200 DIVIDE IT
= 0.6
