A bag contains colored blocks. 3 blocks are pink
4 blocks are yellow
1 block is brown
a block will be randomly selected from the bag. what is the probability in decimal form that the block selected will be yellow?

0.5

Explanation:

3+4+1= 8. So there are 8 blocks in the bag. There are 4 yellow blocks, so there is a 4/8 chance you'll get a yellow block. 4/8 can be simplified to 1/2, and 1/2 in decimal form is 0.5

Hope this helps!

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94
