Question

Cards marked with the number 2 to 101 are placed in a box and mixed thoroughly. One card is drawn from the box. Find the probability that the number on the card selected has an odd number which is not less than 70.

a) 1/3
b) 31/100
c) 15/50
d) 31/50

Answer 1

The probability that the card selected has an odd number which is not less than 70 is 31/100. Thus, the correct answer is b) 31/100.

Step-by-step explanation:

To find the probability that the number on the card selected has an odd number which is not less than 70, we first need to determine the number of cards that meet this condition.

There are 31 odd numbers between 70 and 101 inclusive.

Out of this range, there are 32 numbers in total (101 - 70 + 1).

Therefore, the probability is calculated as 31/32, which simplifies to 31/100.

So, the correct answer is b) 31/100.
