Jerome runs a clothing store. To mark their anniversary, they have a promotional offer for their customers. He has kept a box with five 10% discount coupons, eight 15% discount coupons, seven 20% discount coupons, six 25% discount coupons, and
four 40% discount coupons. Every 30 minutes, one customer gets to draw a discount coupon from the box, use it on their purchase,
and then place the coupon back into the box. Jerome predicts that when a customer draws a discount coupon from box without
looking, the customer will draw a 10% discount coupon one-sixth of the time.
Which activity would best allow Jerome to test his prediction?

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

the correct answer is $7.38
