HI!
First of all, there are total 12 + 2 + 6 = 20 pairs of socks.
Probability of getting a pair of white socks the first time is 12/20.
Probability of getting a pair of gray socks without replacement, if first one was white, is 2/19
Therefore the probability t<span>hat she will take a white pair and gray pair</span> without replacement is 6/95 (I multiplied the two probabilities)
Let me know if there are any other questions!
Hmmm if you don't have a Unit Circle, this is a good time to get one, many you can find online. Anyhow, check your unit circle for cos(30°) and sin(30°).
Step-by-step explanation:
The numerical expression is:
(36 + 14) / (2 * 5).
Answer:
10,000 + 3,000 + 70 + 9
Step-by-step explanation:
It will be 10,000 + 3,000 + 70 + 9
That is how expanded form works.
Hope it helps :)
If you have any questions ask me.
