Eva wants to know the probability of tossing “heads” at least three times out of five. she used the random number table to simulate flipping a coin. she assigned odd digits to represent “heads” and even digits, including zero, to represent “tails.”

use the table to find p(“heads” at least 3 out of 5 times).

To obtain the probability of obtaining heads at least 3 times out of 5 times we recall that in her simulation she assigned odd digits to represent heads and even digits to represent tails. Thus, we count the simulated numbers to see in how many numbers do we have 3 or more odd digits.

Below, the simulated numbers with 3 or more odd digits are bolded.

We have 6 simulated numbers having 3 or more odd digits.
Therefore, P("heads" at least 3 out of 5 times) = 6 / 16 = 3 / 8.
