The second option - 3/25.

The probability of the first one is 3 blue socks over 10 socks in total = 3/10
The probability of the second one is 4 red socks over 10 socks in total = 4/10

Multiply the two probabilities to get the probability of having the first sock as blue and the second sock as red.

3/10 * 4/10 = 3/25

First sock being blue is 3/10
Second sock being red after blue is chosen first is 4/10, because of replacement

3x4=12
10x10=100

divide by 4 to get 3/25

What is the value of the expression 50 - (5 + 2)2 + 6?

Answer:

I believe it's 42

Step-by-step explanation:

Replace each letter in the expression with the assigned value.

First, replace each letter in the expression with the value that has been assigned to it. To make your calculations clear and avoid mistakes, always enclose the numbers you're substituting inside parentheses. The value that's given to a variable stays the same throughout the entire problem, even if the letter occurs more than once in the expression.

However, since variables "vary", the value assigned to a particular variable can change from problem to problem, just not within a single problem.

Perform the operations in the expression using the correct order of operations.

Once you've substituted the value for the letter, do the operations to find the value of the expression.
