Question

You select a marble without looking and then put it back. If you do this 35 times, what is the
best prediction possible for the number of times you will pick a marble that is not purple?
times

Answer 1

Answer:

30 times

Step-by-step explanation:

there are 7 marbles in which 6 are not purple

this means that pulling a non purple marble is a 6/7 chance

you can multiply 6/7 by 35/1 to get your answer

6/7 * 35/1 = 30

30 times you will probably pick a marble that is not purple
