Answer:
16 minutes
Step-by-step explanation:
If it takes 63 minutes to paint 9 walls then it means for every wall, it takes 63/9=7 minutes
Since it is 4 people working for 7 mins, the individual rate is 4/7 minutes per person
When we have 7 people, then the number minutes they take will be 7*4/7=4 minutes per wall
4 min per wall for 4 walls then total time will be 4*4=16 minutes
100%- you can see that the line in the middle goes from 3 to 24

Answer:
1/72
Step-by-step explanation:
Probability of getting a 4 on white cube is:
P(W) · P(4) = 1/2 × 1/6 = 1/12
P(R) · P(>4) = 1/2 × 2/6 = 1/6
multiply both probabilities: 1/12 × 1/6 = 1/72
