the numbered disks shown are placed in a box and one disk is selected at random. find the probability of selecting a 7, given that a green disk is selected.\nfind the probability of selecting a 7, given that a green disk is selected.\n(type an integer or a simplified fraction.)
Answer
Explanation:
Step1: Count green disks
There are 2 green disks shown (labeled 1 and 5).
Step2: Count green - 7 disks
There are 0 green disks labeled 7.
Step3: Calculate probability
The probability of selecting a 7 given a green disk is selected is $\frac{\text{Number of green - 7 disks}}{\text{Number of green disks}}=\frac{0}{2} = 0$.
Answer:
0
