There are 5 sock in a bag 2 of those socks are blue what is the probability of picking a blue sock randomly from the bag

P(blue sock)  = 2/5

Step-by-step explanation:

There are 2 blue socks of the total 5 socks

P(blue sock) = blue socks/ total socks

                      = 2/5

The chance of picking a blue sock is 40%.

Step-by-step explanation:

There are 5 socks in all. 2 of the socks are blue. This means that 2 out of the 5 socks (2/5) are blue.

The probability can be found by changing the fraction to percentage. To do so, make the denominator 100. Remember that what you do to one denominator, you must also do to the numerator. Multiply 20 to both top and bottom.

(2/5)(20/20) = (2 * 20)/(5 * 20) = 40/100

Change the fraction to percentage.

40/100 = 0.40 = 40%

The chance of picking a blue sock is 40%.

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
