Ted tossed a coin several times and recorded the number of heads and tails in the following table:
coin experiment side of coin number of tosses
heads 18 tails 22
what is the experimental probability of getting heads?
a. 0.18
b. 0.22
c. 0.35
d. 0.45

Option: D is the correct answer.

                     D.  0.45

The results of the experiment are given as follows:

Coin Experiment Side of CoinNumber of Tosses

                              Heads                           18

                               Tails                             22

This means that total 40 experiments were performed.

( Since 18+22=40)

Also, the number of times head turn up=18

Hence, the experimental probability of getting heads is:

Ratio of number of times head turn up to the total number of experiments performed.

Hence,

   Hence, the experimental probability of getting head is:

                                         0.45
