Harris Interactive recently reported that 33% of U. S. adults believe that finding and picking up a penny is good luck. Suppose this percentage is true. Assuming responses from different individuals are independent, what is the probability of selecting 10 U. S. adults and finding at least one who believes that finding and picking up a penny is good luck?

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

im not sure of the names, but the answer is 48
