Answer: lump sum investment
Step-by-step explanation:
No offense to the person above me but they are wrong. So first you have to examine the probability of the first card being blue. Since there are 20 total cards, and three are blue, the probability of the first card being blue is 3 out of 20 or 3/20. Now examine the probability of the second card being blue. Since the previous card was replaced, the total number of cards is still 20. Three out of 20 cards are blue (just like before), so the probability of the second card being blue is 3/20. But the answer is NOT 3/20. Because you have to multiply the two probabilities together because it is happening back to back (if that makes sense). So multiply the two fractions. 3/20 times 3/20 = 9/400. So your ANSWER IS 9/400. (I just put it in caps so it’s easy to see) The fraction can’t be simplified any further. Hope this helps!

Answer:
0.11
Step-by-step explanation:
To get the probability above, we simply look for the events greater than 4, then add their probabilities
That is;
P(5) + P(6) + P(7)
So the probability in this case will be;
0.07 + 0.03 + 0.01 = 0.11
