PLEASE HELP!! WILL BE GIVING BRAINLIEST TO THE CORRECT ANSWER!!!
anyanavicka [17]

Answer:

E(x) = 99

Step-by-step explanation:

Given

The attached table

Required

Number of times 3 or 4 will occur

First, we complete the table as follows:

P(1) + P(2) +......+P(6) =1

0.13 + 0.05 + P(3) + 0.21 + 0.19 + 0.3 = 1

Collect Like Terms

P(3)= 1 -(0.13 + 0.05  + 0.21 + 0.19 + 0.3 )

P(3)= 0.12

The expected number of times is:

E(x)= n * P(x)

So, we have:

E(x) = 300 * (0.12 + 0.21)

E(x) = 300 * (0.33)

E(x) = 99

What’s the answer to f(a)
S_A_V [24]

Answer:

The answer to this is fa

Step-by-step explanation:

This is because you as the solver doesn't know what the variables f or a is so you put them together as multiplication until you do understand what f and a are so you can multiply them.

If you were to graph this it would be a horizontal line going infinite in both directions. That means no slope or y axis.
