14. The student is not correct because ...
Ex. 14:6 if you add one to
5 odd numbers and 5 even numbers
since they can be repeated
5*5*5=first 3 digits
5*5*5=last 3 digits
in all
5*5*5*5*5*5=15625 ways
Answer:
The probability of selecting a red or green marble is 0.6923.
Step-by-step explanation:
Let's denote the events as follows:
<em>R</em> = a red marble is chosen
<em>G</em> = a green marble is chosen
The information provided is:
n (R) = 7
n (G) = 5
n (R ∩ G) = 3
Total number of marbles in the bag is, N = 13.
The probability of an event <em>E</em> is:
Compute the probability of selecting a red or green marble as follows:
P (R ∪ G) = P (R) + P (G) - P (R ∩ G)
Thus, the probability of selecting a red or green marble is 0.6923.
