The total number of outcomes is (1/2)^5 dice each of the 5 coin tosses is an independent event. From the 5 possible tails, exactly 2 tails need to be selected. So the favored outcome is 5C2 = (5*4)/(1*2)= 10. The probability is 10/32 = 5/16.
Yes. Half of 2.5 is 1.5; this is the amount he would need for 1 dozen cookies. Multiply 1.5 by 3 will give you 3.5.

Answer:
D. 28 +10i
Step-by-step explanation:
As with any "collect terms" problem, you first identify the like terms, then add their coefficients. You can start with either the real or the imaginary terms to obtain a result that will point you to the correct answer choice. Of course, the distributive property works in the usual way.
(3i+ 4) -i + 4(6 +2i) = 3i +4 -i +24 +8i . . . . eliminate parentheses
= (4 +24) +(3 -1 +8)i . . . . . . . group like terms
= 28 +10i
