3. Given X and Y are two events such that P(X) = 5,P(Y) = and P(Xn Y) = . Find P(Y|X).
4. A firm has 500 workers. As many as 80% of them play football, 75%
play hockey, 50% rugby and 36% play all the three games. 35 of the
workers play only football and 32 of them play only hockey while 203 of them play both hockey and rugby .Show allvthe information clearly in a Venn diagram . if a worker is selected at randon, what is the probability that he / she plays football given that he/she also plays hockey?

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°

answer: 0.64
