Simplify:
A -6i
B 6i (sqrt 2)
C -6i (sqrt -2)
D 6i

A and D

Step-by-step explanation:

Given

= ±

= ± ×

= ± 6i

That is - 6i or 6i

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
