Step-by-step explanation:
so we're making two draws *with* replacement (this is important)
step 1: for the first draw, it wants the probability of getting a sour candy. to calculate this:
(# of sour candy) / (total # of candy)
step 2: for the second draw, it wants the probability of *not* getting a sour candy. to calculate this, you can calculate 1 - (the probability form part 1).
step 3: to find the probability of both events happening together, simply multiply the probabilities from part 1 and 2 together
side note: for step 2, you can only do this because the candy is being replaced. if there were no replacement, you'd have to re-calculate (# of non-sour candies) / (total after the first candy is drawn)

Answer:
63 calories
Step-by-step explanation:
Divide the number of calories by the number of servings
calories/servings
252/4
63
So, there are 63 calories per serving

Answer:
183.92 inch²
Step-by-step explanation:
To find the total amount of wrapping paper needed, you must find the Surface Area of the box.
Surface area of a rectangular prism is: A = 2(<em>wl</em> + <em>hl</em> + <em>hw</em>)
w = width = 3.8
h = height = 9.5
l = length = 4.2
Plug in the corresponding numbers to the corresponding variables.
A = 2(<em>wl</em> + <em>hl </em>+ <em>hw</em>)
A = 2((3.8 * 4.2) + (9.5 * 4.2) + (9.5 * 3.8))
Simplify.
A = 2((15.96) + (39.9) + (36.1))
A = 2(15.96 + 39.9 + 36.1)
A = 2(91.96)
Multiply.
A = 183.92
183.92 inch² is your answer.
