Ryan’s mom randomly chooses two days each week for ryan to do his chores. what is the probability that she picks saturday and sunday?

Probability that she picks Saturday and Sunday = 1/21 = 0.0476

Step-by-step explanation:

Total number of days in a week = 7

Number of days selected = 2

Total number of combinations = 7C₂

Total number of favorable ways = 1 that is  Sunday and  Saturday.

Probability that she picks Saturday and Sunday = 1/21 = 0.0476

B. 137.32 cm3

Step-by-step explanation:

So what we know is that

Height = 12

Diameter is 6 which would make the radius 3.

The current volume is 339.12

12cm × 1.12 = 12.44 (This is the new height.)

3cm × 1.12 = 3.36 9 (This is the new radius)

Volume of future can (V2) = πr²h = 3.14 × 3.36 ×3.36 × 13.44 = 476.43

Then you would subtract  476.43(new volume) - 339.12(old volume) = 137.31

That would round to 137.32 cm3.

So the answer is B. 137.32 cm3.
