Suppose that 30% of flies are black, and 70% are grey. two flies are chosen at random, what is the probability that the chosen flies are both grey? ( round to 2 decimal places)

Probability of choosing a black fly = 30/100 = 0.3

Probability of choosing a grey fly = 70/100 = 0.7

So, probability of choosing 2 grey flies = 0.7*0.7 = 0.49

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
