The first is independent of one another because the probabilities of picking the marbles doesnt change because the first marble was placed back in. Now the second one is dependent because the first card picked wasnt placed back which changes the probability of the rest of the cards.

Answer:
x = 90
Step-by-step explanation:
2(45° ) + x = 180°
Distribute
90 +x = 180
Subtract 90 from each side
90+x-90 =180-90
x = 90
Answer:
0.9544
Step-by-step explanation:
P(-2 < Z < 2) means that Z has mean 0 and standard deviation 2.
P(−2 < Z < 2) = F(2) - F(-2)
Using the Z - table,
F(2) = 0.9772
and F(-2) = 0.0228
Thus,
P(−2 < Z < 2) = 0.9772 - 0.0228 = 0.9544
This means that data within two standard deviation is 95%.
