Not 100% sure what to do here can you explain?
Answer:
44.4%
Step-by-step explanation:
The probability in this case would be the specific number of pairs of means that we are asked to calculate, that is, blue divided by the total number of pairs, which would be the sum of the different colors, then:
We have that blue there are 4 pairs, and in total it would be 2 + 4 + 3 = 9, that is to say 9 pairs of means.
therefore the probability is:
4/9 = 0.444
Which means that there is a 44.4% chance of drawing a blue pair.

Answer:
15 bikes, 6 gocarts
Step-by-step explanation:
so both the vehicles have 1 seat each
the bicycles will be represented by B
the gocarts will be represented by G
because there are only 1 seat per for a total of 21 seats, we have this as the first equation:
B + G = 21
Gocarts have wheels and bikes have 2 seats, so we have this equation:
2B + 4G = 54
from there we can simply replace b with g to find the amount of gocarts first:
B + G = 21
B = 21 - G
2(21-G) + 4G = 54
42 - 2G + 4G = 54
2G + 42 = 54
2G = 12
G = 6
So there are 6 gocarts.
plug in 6 for g
B + 6 = 21
B = 15
therefore, there are 15 bikes and 6 gocarts
