Answer:
1/5
Step-by-step explanation:
We assume the events are independent, so the probability of the joint event is the product of the probabilities of the individual events.
P(Y or W) = 2 letters of 5 = 2/5
P(easy) = 1 of 2 kinds = 1/2
The product of these is ...
P((Y or W) and (easy)) = (2/5)(1/2) = 1/5
_____
In both cases, we have to assume that each of the possible outcomes is equally likely.
Answer:
x = -7 - 17/20 or -157/20
Step-by-step explanation:
2x/3 - 3.2 = -8.1
2x - 9.6 = -24.3
20x - 96 = -243
20x = -157
x = -157/20
x = -7 - 17/20
Answer:
X is 24.

Answer:
-12.5%
Step-by-step explanation:
The percentage change in your time can be computed using ...
pct change = ((new value)/(old value) -1) × 100%
= (28/32 -1) × 100%
= (0.875 -1) × 100% = -12.5%
The time to finish level 2 decreased by 12.5%.
