Which event would be closest to having a probability of occurring of 0.8?

a) choosing a vowel from the set {a, e, i, o, u}

b) choosing an odd number from the set {2,4,6,8,9}

c) choosing a consonant from the set {b, c, d, e, f}

d) choosing an even number from the set {1,3,5,7,9}

Plz hurry. AND NO LINKS PLZ

c) choosing a consonant from the set {b, c, d, e, f}

Step-by-step explanation:

Since all of the choice sets have 5 values each, a 0.8 chance = 80% = .

So find the set with 4 values that meet the criteria.

A: 5/5 = 1 = 100%

B:  1/5 = 0.2 = 20%

C: 4/5 = 0.8 = 80%

D: 0/5 = 0 = 0%

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
