Question

Mark is rolling a six-sided number cube repeatedly. His goal is to roll an odd number 17 times. How many times should Mark expect to have to roll the number cube for an odd number to be rolled 17 times? Enter your answer in the box to correctly complete the statement Mark should expect to roll the number cube approximately times to roll an odd number 17 times.​

Answer 1

Answer: 34

======================================================

Step-by-step explanation:

The odd numbers show up half of the time, on average.

So if x is the number of rolls, then 0.5x is the number of times we expect an odd number to show up. Set this equal to 17 and solve for x.

0.5x = 17

x = 17/0.5

x = 34

If Mark rolled the cube 34 times, then about half of those rolls (0.5*34 = 17) he should expect to get an odd number.

Answer 2

34 times

Step-by-step explanation:

a six-sided cube has 3 odd number and 3 even numbers a 50/50 chance of getting an odd number. 17 + 17 = 34
