it takes 63 minutes for four people to paint nine walls how many minutes does it take seven people to paint four walls?

joja [24]

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

ZanzabumX [31]

Answer:

Step-by-step explanation:

Given that two fair dice, one blue and one red, are tossed, and the up face on each die is recorded.

a) P(E) = P(the difference of the numbers is 3 or more}

Favourable events are (1,4) (1,5)(1,6) (2,5) (2,6) (3,6) (4,1) (5,1) (5,2) (6,1) (6,2)(6,3)

P(E) = $\frac{12}{36} =\frac{1}{3}$

b)P(F)

Favourable events for F = (1,1) (2,2)...(6,6)

P(F) = $\frac{6}{36} =\frac{1}{6}$

c) P(EF)

There is no common element between E and F

P(EF) =0
