How many times would a coin have to show heads in 50 tosses to have an experimental probability of 20% more than the theoretical probability of getting heads? 10 25 35 45

Hence, the number of heads that turn up is:

35.

Step-by-step explanation:

We have to find the number of times would a coin have to show heads in 50 tosses to have an experimental probability of 20% more than the theoretical probability of getting heads.

We know that

The theoretical probability of getting head is 50% for a fair coin. Since the experimental(the actual) probability is 20% more

Hence  the experimental probability is 50+20=70%.

Now,

70% percent of the coin tosses are heads i.e.

Hence, the number of heads are:

35
