Question

Vanessa has a lot of headbands. Twenty are pink, 32 are blue, and 16 are black. If she picks a headband at random, what is the probability that it will not be black?

Answer 1

`(13)/(17)`

Explanation:

all headbands: 20+32+16 = 68

headbands that aren't black: 68-16 = 52

the probability:
`(52)/(68)=(13)/(17)`
