In a random survey of students concerning student activities, 30 engineering majors, 23 business majors, 20 science majors, and 14 liberal arts majors were selected. (Enter your probabilities as fractions.) (a) If two students are selected at random, what is the probability of getting two science majors?

(b) If two students are selected at random, what is the probability of getting a science major and an engineering major?

1 ?

step-by-step explanation:

u said 1+1+1+1+1+1+1+1+1+1+1+1*0 so ur adding 1 but then multiplying by 0 so its 0 but then u said 1*0+1 so now ur adding 1 so the answer is juan ?

~leah

i believe it’s 165 because if u add 137 and 58 u get 195 and then subtract that from 360 and there’s ur answer

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
