Billy's prism will require more material by 30 square cm

Step-by-step explanation:

Billy's Prism: 2cm, 8cm, & 10cm

2lw + 2lh + 2wh - Formula for Surface Area (l = length, w = width, & h = height)

2(2)(8) + 2(2)(10) + 2(8)(10)

= 32 + 40 + 160

= 232 cm squared

Charlie's Prism: 9cm, 5cm, & 4cm

2lw + 2lh + 2wh - Formula for Surface Area (l = length, w = width, & h = height)

2(9)(5) + 2(9)(4) + 2(5)(4)

= 90 + 72 + 40

= 202 cm squared

Billy's Prism - Charlie's Prism = 232 - 202 = 30 cm squared

So, Billy's prism will require more material by 30 square cm

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
