Question

Two friends, Bob and Ben, each buy one lottery ticket. Each ticket contains six numbers from a total of one hundred numbers (0–99). Bob chooses the numbers 1, 2, 3, 4, 5, 6, and Ben chooses the numbers 39, 45, 66, 72, 74, 89. Who has a higher probability of winning?

A-Ben

B-Bob

C-both have an equal chance

D-insufficient information

Answer 1

We can assume that there is one winning number. Each number on a ticket represents a random selection of a number from 0 to 99. Therefore each number has a probability of 1/100 of being the winning number. Six different numbers have a 6/100 probability of containing the winning number. Can you see the correct choice now?

Answer 2

No 😭

Answer 3

they are equal chances
