A medicine is effective for 80% of patients. The table shows 30 randomly generated numbers from 0 to 999. Use the table to estimate the probability that the medicine is effective on fewer than two of the next three patients. Let the digits 1 through 8 represent the medicine being effective.

Answer 1

1/2 and 1/10

Explanation:

trust me!!!!

Answer 2

1/2 & 1/10

Explanation:

Each of three:

15 outcomes have all three digits 1 through 8

So, 15/30 which is 1/2

Fewer than 2 is one or none being effective, i.e one or no digits are 1 through 8

There are only three such outcomes

So, 3/30 = 1/10
