In recent survey, 30 percent indicated chocolate was their favorite flavor of ice cream. Suppose we select a sample of twelve people and ask them to name their favorite flavor of ice cream.

(a) How many of those in the sample would you expect to name chocolate? (Round your answer to 4 decimal places.)

(b) What is the probability exactly seven of those in the sample name chocolate? (Round your answer to 4 decimal places.)

(c) What is the probability seven or more name chocolate? (Round your answer to 4 decimal places.)

it is C What is the probability seven or more name chocolate? (Round your answer to 4 decimal places

Step-by-step explanation:

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
