Given P(X) = 0.5, P(Y) = 0.4, and P(Y|X) = 0.3, what are P(X and Y) and P(X or Y)?

P(X and Y) =0.2, P(X or Y)=0.7

Step-by-step explanation:

P(X or Y)

P(X∪Y) = P(X)+P(Y) - P(X∩Y)

=  0.5 + 0.4 - 0.2

=  0.7

or 1-P(Y|X)=1-0.3=0.7

P(X and Y)

P(X∩Y) = P(X) × P(Y)

=  0.5 × 0.4

=  0.2

I hope it helps

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.
