Answer:
Pr(B) = 0.69
Pr(J/B) = 0.35
Pr(J∩B) = 0.14
Pr(G/J') = 0.66
Pr(G) = 0.31
Step-by-step explanation:
Applying,
Pr = possible outcome (a)/Total outcome(t)
(1) Pr(B) = a/t............ Equation 1
From the diagram
Given: a = 220+65+35 = 320, t = 220+65+35+145 = 465
Substitute these values into equation 1
Pr(B) = 320/465
Pr(B) = 0.69
(2) Pr(J/B) = (35+65)/(220+65)
Pr(J/B) = 100/285
Pr(J/B) = 0.35
(3) Pr(J∩B) = 65/465
Pr(J∩B) = 0.14
(4) Pr(G/J') = 145/220
Pr(G/J') = 0.66
(5) Pr(G) = 145/465
Pr(G) = 0.31
Answer:
The time required them working together to shovel the snow is T = 1.428 hours
Step-by-step explanation:
Given data
Time taken by first person to shovel the snow
= 2 hours
Time taken by second person to shovel the snow
= 5 hours
Time taken by both persons to shovel the snow

Put all the values in above equation we get

T = 1.428 hours
Therefore the time required them working together to shovel the snow is T = 1.428 hours
