Answer:

p = 0.55

Step-by-step explanation:

By looking at the "total" part, we can see that:

There are 20 people surveyed in this case.

We can see that 11 of these play an instrument.

The probability that a person selected at random plays an instrument can be estimated as the relative frequency of people that play an instrument in this survey.

Then the relative frequency of people that play instruments, is equal to the quotient between the number of people that play an instrument and the total number of people surveyed, this is:

p = 11/20 = 0.55

So, we can assume that the probability wanted is 0.55
