Question

In an experiment, a coin is tossed 600 times, if the tail turns up 240 times. Find the experimental probability of getting:(i) A head (ii) A tail

Answer 1

Answer:

let E1 be the probability of getting a head=600-240

=360

p(E1)=no of elements of E1÷total no of possibilities

=460÷600=3÷5

b)let E1 be the probability of getting tail =240

p(E1)=no of elements of E1÷total no of probabilities

240÷600

=1÷5

Answer 2

Given,

• Total number of times a coin is tossed = 600
• Number of times Tail turns up = 240

To find,

The experimental probability of getting:

• a head
• a tail

Solution,

In an experiment, a coin is tossed 600 times, if the tail turns up 240 times, then the experimental probability of getting a head is 6/10 and a tail is 4/10.

Total number of times a coin is tossed = 600

        Number of times tail turns up = 240

        Number of times head turns up = 600-240

                                                              = 360

  Probability = favorable cases/ Total number of cases

P( of getting a head) = 360/600

                                  = 6/10

    P( of gettig a tail) = 240/600

                                  = 4/10

Hence, in an experiment, a coin is tossed 600 times, if the tail turns up 240 times, then the experimental probability of getting a head is 6/10 and a tail is 4/10.
