One hundred draws will be made at random with replacement from the box 1 6 7 9 9 10 . (a) how small can the sum of the draws be? how large? (b) the sum is between 650 and 750 with a chance of about 1% 10% 50% 90% 99%

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%

1/2(2*4)=6 $$- agahajakanajak
