Samantha believes that the probability of her winning the gymnastics meet is 3/8. what is the probability of her losing the gymnastic meet

Hello there!

Ok, in this case, there are only two probabilities, one where Samantha wins, and one where Samantha losses.

In statistics, when we are loockin to a particullar event, all rhe probabilities should add to 1. In this case, the probability of samantha winning plus the probability of Samantha losing should be equal than one.

then:

3/8 + x = 1

x= 1 - 3/8 = 5/8

and this makes a lot of sense, if there are 3 of 8 scenarios where Samantha wins, then we have other 5 of 8 scenarios where Samantha doesn't win.

207/8 is the right

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
