Consider rolling two fair dice and observing the number of spots on the resulting upward face of each one. Letting A be the even

Allushta [10]

Answer:

$P(E|A)= \frac{10}{11}$

Step-by-step explanation:

Given

Two rolls of die

$E \to$ one of the outcomes is 6

$A \to$ atleast one is 6

Required

P(E|A)

First, list out the outcome of each

$E = \{(1,6),(2,6),(3,6),(4,6),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5)\}$

$A = \{(1,6),(2,6),(3,6),(4,6),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6)\}$

So:

$P(E|A)= \frac{n(E\ n\ A)}{n(A)}$

Where:

$E\ n\ A = \{(1,6),(2,6),(3,6),(4,6),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5)\}$

$n(E\ n\ A) = 10$

$n(A) = 11$

So:

$P(E|A)= \frac{10}{11}$

What is the area of a sector that has a radius of 25 mm and has an angle measure of 50

attashe74 [19]

Answer : The area of sector is, $272.57mm^2$

Step-by-step explanation :

Formula used to calculate the area of sector in degree is:

Area of sector = $\frac{\theta}{360}\pi r^2$

where,

$\theta$ = angle = $50^o$

r = radius = 25 mm

Now put all the given values in the above formula, we get:

Area of sector = $\frac{\theta}{360}\pi r^2$

Area of sector = $\frac{50}{360}\times 3.14\times (25)^2$

Area of sector = $272.57mm^2$

Therefore, the area of sector is, $272.57mm^2$
