Answer:
D
Hey There!
To find the answer you have to add the frequencies of all of them and take the frequency of 3 people being in a car and divide that by the sum of all of the frequencies if that makes sense
37+98+40+25=200
The frequency of 3 people being in a car is 40
so we would do
which is equal to
Therefore D is your answer
Answer:
The probability of selecting a red marble, not replacing it, and then selecting a green marble from the bag is 24/95
Step-by-step explanation:
Number of red marbles = 12
Number of green marbles = 8
Total number of marbles = 12+8 = 20
Probability of selecting red marble =
Since it is the case of no replacement
Remaining marbles = 20-1 = 19
Number of red marbles = 12-1=11
Number of green marbles = 8
Probability of selecting green marble =
So, the probability of selecting a red marble, not replacing it, and then selecting a green marble from the bag =
Hence the probability of selecting a red marble, not replacing it, and then selecting a green marble from the bag is 24/95
