Answer 1

I can't answer this question.

Explanation:

There is no "shown spinner", so I have no clue as to what the answer is or could be. Maybe try attaching a photo?

Answer 2

A) 60

B) 72/300

C) 150

Explanation:

A) P(green) = ⅕

⅕ × 300 = 60

B) purple: 72

45+37+52+94+72 = 300

Therefore, 72/300

C) 1000 × (45/300)

150
