25% because 21 is a quarter of 84. And 21 times 4= 84, so 21 is 25% of 84.

We set up a proportion: 21/84= ?/100

Cross multiply: 84*?= 21*100
⇒ ?= 21*100/84= 25

25% of 84 is 21.

On a fair, 8-sided die, each face is painted as follows: the 1 and 2 are painted green, 3 through 6 are painted blue, 7 is paint
Alinara [238K]

Answer:

0.25

Step-by-step explanation:

outcomes painted in blue: {3, 4, 5, 6}

number of even outcomes painted in blue: 2

number of total outcomes: 8

Therefore, the probability that the roll will show an even number and a face that is painted blue is: 2/8 = 0.25
