Question

coin is tossed a hundred times ,no. of heads turn up is 68,find the probability of getting tails

Answer 1

obvisoly 100 minus 68.....!!! may beee 38 I don't know properly

Answer 2

Answer:

8/25

Step-by-step explanation:

the sample space of this event of tossing coins is only 2. that is the heads and tails.

since the heads is given,

p(heads)=68/100

= 17/25

also,

the sum of probability of the events = 1

p(heads) + p(tails) = 1

p(tails) = 1 - p(heads)

= 1 - 17/25

=(25-17)/25

=8/25

therefore the probability of getting tails = 8/25
