Abox contains cards that are numbered from 1 to 100. What is the probability of randomly selecting a number that is less than 12?

11/100

Explanation:

There are 11 numbers that are less than 12 from 1-11

Which mean there are 11 possibilities of choosing a number less 12 from the 100 cards.

We can write that probability:

P = 11/100

Therefore, the probability of choosing a number less than 12 in a box of 100 cards is 11/100.

40%=2/550=1/230=3/1056=14/25

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
