Answer:
A. 1/8
Step-by-step explanation:
Let
P(A) be the event that white marble is drawn
P(B) be the event that black marble is drawn
P(A) = 1/4
P(B) = 1/2
Both events A and B are independent as the first marble is put back before drawing the second marble. So the probabilities of two independent events are multiplied.
P(A and B) = P(A) * P(B)
= 1/4 * 1/2
=1/8
Option A is the correct answer..
Answer:
54i - 8
Step-by-step explanation:
6*9i + 4i*2i
=54i + 8i^2
= 54i - 8
Answer: $840
Step-by-step explanation:
- Set up the proportion 210/10 = x/40.
- To solve it quickly, multiply 210 with 4, since 10*4 = 40. Therefore, x = 840.
