11. The "Eyland Grrls"; Sofia (No Waay!), Samantha (Ghet Da Stat Out!), Britney (Oh Shift!) and Logan (Smak Dat Stat), wanted to find the number of tune-ups per month necessary for the new LASERNA sports car. They sent their top executives Edward and Doug (of "Reject Jose, he's Shady!") and they came up with the following results: Tune-ups 0 1 2 3 4 5 6 Probability .04 10 .23 .30 .16 .12 .05 Find: a. (2pts.) The probability that the LASERNA sports car needed no more than 2 tune-ups in a month. b. (2pts.) What was the average number of tune-ups per month? c. (4pts.) Find the variance and the standard deviation for the number of tune-ups in a month
