Question

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

Answer 1

The chance of picking a blue sock is 40%.

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%.
