There are 4 red, 6 yellow and 6 blue socks in the drawer. if the sock is not replaced after it is drawn, what is the probability of drawing a red and then a blue sock? (find probabilities and multiply)

Total amount: 16

Red socks: 4

Probability of picking a red sock 4/16

If we take a red sock out and do not replace it, we are left with a total of 15 socks.

Blue socks: 6

So the probability of picking a blue sock will be 6/15

Multiply:

4/16 * 6/15 = 24/240 = 1/10

Answer d; a supplementary angle = 180°, so if that angle = 150°, y would = 30°.
