Answer:
Step-by-step explanation:
Number of Headband Types=3
P(Reese will choose a blue headband)=1/3
Number of Types of Necklace=2
P(Reese will choose a silver necklace)=1/2
Number of Types of Earrings=3
P(Reese will choose a silver earrings)=1/3
In Probability Theory,
P(A AND B)=P(A) X P(B)
Therefore, the probability that Reese will choose a blue headband, a silver necklace, and a silver pair of earrings

Answer:
400 square inches
Step-by-step explanation:
surface area= summation of area of all the faces the object has
out object has 2 triangular faces, and 3 rectangular faces
S.A = 2(0.5bh) + LW +LW+LW
= 2(0.5 x 8 x 15) + (15x7) + (17 x 7) + (7×8)
= 120+105+119+56
= 400 square inches
