Seventy-five percent of the flowers in the arrangement are roses and the rest are tulips. of the tulips, 50 percent are pink.

to the nearest whole percent, what is the probability that a randomly chosen flower from the arrangement is a pink tulip?

Okay, so what we know so far is that 75/100 flowers are roses, and 25/100 are tulips.

Now out of the 25/100 tulips, only 50% of that are pink.

Therefore, the probability of randomly picking a pink tulip is 1/2 * 25/100 = 25/200

25/200 in a percentage form is 13%
