Step-by-step explanation:
20*3/4 = 60/4....and 60/4 = 15
(a)well, a is 8 / 2,000, which is 1 /250. that means for every 250 bowls, one is chipped
(b)from there, you figure out what times 250 will get you to 10,000. in our case, its 40.
To start off with, the probability to draw the short straw is 1/9 and each time someone picks the long straw the denominator (the 9) decreases by one which means that the odds of someone picking it get higher.
