In my opinion, this question can not be answered unless you know how many pinecones at least one girl has. Both girls could have any number of pinecones that both, together in total, amount to 31. See what I'm saying?

Solve Step by Step: 

1) Write the Equation: 31/2 = how many pine cones Jenna and Ellen found.
2) Solve 31/2= 15.5

So each girl found 15 and a half pine cones. Or one girl found 15 and the other found 16. If you want to have each girl find an even amount.

Write the product in simplest form: -8w * (-w)
Hitman42 [59]
8w

-8w times -w is like -8*-1 which would just make the number positive.

A positive integer from one to six is to be chosen by casting a die. Thus the elements c of the sample space C are 1, 2, 3, 4, 5
Alex_Xolod [135]

Answer with Step-by-step explanation:

We are given that six integers 1,2,3,4,5 and 6.

We are given that sample space

C={1,2,3,4,5,6}

Probability of each element=\frac{1}{6}

We have to find that P(C_1),P(C_2),P(C_1\cap C_2) \;and\; P(C_1\cup C_2)

Total number of elements=6

C_1={1,2,3,4}

Number of elements in C_1=4

P(E)=\frac{number\;of\;favorable \;cases}{Total;number \;of\;cases}

Using the formula

P(C_1)=\frac{4}{6}=\frac{2}{3}

C_2={3,4,5,6}

Number of elements in C_2=4

P(C_2)=\frac{4}{6}=\frac{2}{3}

C_1\cap C_2={3,4}

Number of elements in (C_1\cap C_2)=2

P(C_1\cap C_2)=\frac{2}{6}=\frac{1}{3}

C_1\cup C_2={1,2,3,4,5,6}

P(C_1\cup C_2)=\frac{6}{6}=1
