Answer:
P (black) = 2/7
Step-by-step explanation:
We need to know the total amount of marbles.
2 red + 3 green + 2 black = 7 marbles
P ( black) = number of black marbles / total marbles
= 2 /7
It should be 2:7 (or, written as a fraction 2/7)
you have to do 52 divided by cos of 38 to get the answer of 65.99ft
1128
