Question

Suppose an experiment consists of randomly generating the digits 1-9, if the experiment were repeated 90 times, how many times would you predict the generated digit to be odd

Answer 1

odd numbers are 1,3,5,7,9
5 out of 9 of all the numbers are odd

5/9 of all outcomes are expected to be odd
90 times
5/9 times 90=450/9=50

50 times it will be odd

Answer 2

the answer is 810 the digit would be 9 then you multiply by 90 it is 810

I hoped this helped!
