Question

A random number generator is used to create a list of 200 single-digit numbers. Of those 200 numbers, 105 are even and ninety-five are odd. Seven was generated fifteen times. What is the experimental probability of an odd number other than seven being generated?

Answer 1

The answer is 40.0%. It is correct I seen the answer.

Answer 2

0.4 or 40%

Explanation:

The total number of trials in this case is 200, since there were 200 single-digit numbers generated.

Of those 200, we know that 95 of them were odd. Of the 95 odd numbers, seven was listed 15 times; this leaves us

95-15 = 80 odd numbers that were not the number 7.

This is 80 numbers out of a possible 200; this is 80/200, which simplifies to 40/100 = 0.4, which is the same as 40%.
