Answer:
Let's denote students in D = in the drama club , S = in a sports team
P(D) = 85/330
P(S) = 200/330
P(D and S) = 60/300
P(D or S) = P(D) + P(S) - P(D and S) = 85/330 + 200/330 - 60/330 = 15/22
P(neither D nor S) = 1- 15/22 = 7/22
Step-by-step explanation:
Answer:
45 cm
Step-by-step explanation:
perimeter of a square is 4 equal sides. each is therefore 200 cm ÷ 4 = 50 cm each.
if each side is dilated by a factor of 0.9
then 50 cm × 0.9 = 45 cm
There are 35 ways to get a sum of at least 3 when rolling 2 dice.
Out of the 36 possibilities, the only way to NOT have a sum of at least 3 is by rolling two 1's.
According to the table, when x = 2, y = 12, and when x = 6, y = 4. We fit them into the slope formula like so:
.
The slope of the line between the two points is -2.
