Answer:

It would be B. 8x3/5

Step-by-step explanation:

So when multiplying fractions, you multiply the denominator of one fraction by the denominator of the other. You then multiply the numerator of one fraction by the numerator of the other.

The 8, can be turned into fraction form by thinking of it as 8/1 x 3/5.

And thinking about how we do denominator x denominator, numerator x numerator, it will look like:

\frac{8*3}{1*5}

There is one more thing we need to simplfy before we will get our answer.

When you multiply a number by 1, what do you get? The same exact number as before.

Sp tecnically, 1*5 would just be 5:

\frac{8*3}{5}

This looks like answer b!

Hope this helps!

Sunny_sXe [5.5K]

Answer:

E (Y) = 3

Step-by-step explanation:

If a 4-sided die is being rolled repeatedly; and the odd-numbered rolls (1st 3rd,5th, etc.)

The probability of odd number roll will be, p(T) = \frac{1}{2}

However, on your even-numbered rolls, you are victorious if you get a 3 or 4. Also, the  probability of even number roll, p(U) = \frac{1}{2}

In order to  calculate: E (Y); We can say Y to be the number of times you roll.

We know that;

E (Y) = E ( Y|T ) p(T) + E ( Y|U ) p(U)

Let us calculate E ( Y|T ) and E ( Y|U )

Y|T ≅ geometric = \frac{1}{4}

Y|U ≅ geometric = \frac{1}{2}

also; x ≅ geometric (p)

∴ E (x) = \frac{1}{p}

⇒ \frac{Y}{T} = 4 ; also \frac{Y}{U} = 2

E (Y) = 4 × \frac{1}{2} + 2 ×

        = 2+1

E (Y) = 3

8 = 4w/3

  8 = 4w/3 
×3 = 4w×3
