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) =
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) =
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 =
Y|U ≅ geometric =
also; x ≅ geometric (p)
∴ E (x) =
⇒ = 4 ; also = 2
E (Y) = 4 × + 2 ×
= 2+1
E (Y) = 3
Answer:
x + y = 330 and 9x + 16y = 4650
Step-by-step explanation:
At a museum, the admission price for children is $9 and the admission price for adults is $18. The total amount the museum collects in admissions for the day is $4959. The total number of visitors is 319.
x = number of children
y = number of adults
x + y = 330
9x + 16y = 4650
The different ways that they can vote is given as 16 different ways.
<h3>How to calculate the ways that they can vote</h3>
The question say that there are a total of 4 members of the board. Out of these 4, we have the choices as yes or a no.
This tells us that each person only has 2 choices of what they want.
Hence given that the board members ar 4, we would have 2⁴
= 2 * 2 * 2 * 2
= 16
Hence the different ways that they can all vote is 16.

Angle 3 = 180° - 70°
Angle 3 = 110°
Angle 2 = 180° - (110° + 36°)
Angle 2 = 180° - 146°
Angle 2 = 34°
Angle 4 = 180° - 70°
Angle 4 = 110°
Angle 5 = 180° - (110° + 62°)
Angle 5 = 180° - 172°
Angle 5 = 8°
I hope this helps.
