1. A bag has tiles with two-digit numbers (10-99) on them. A random tile is 4 points
drawn. Find the probability of drawing a 32.
1/99
1/90
1/10
1/2
1/32

Step-by-step explanation:

The probabilty is defined as the ratio between the total events and the total outcomes possible.

In this case, we have 90 total outcomes, which are all two-digit numbers. The event is only one, the number 32. Using the definition, we have

Therefore, the right answer is B.

Correct option: Second one -> 1/90

Step-by-step explanation:

We have numbers from 10 to 99.

First we need to find how many numbers there are, and we can do that subtracting 99 from 10 and then we sum 1, as the values 10 and 99 are also included:

Number of tiles = 99 - 10 + 1 = 90

If we have 90 tiles, and only one of them has the value 32, the probability of drawing a 32 is:

P = 1/90

Correct option: Second one
