Suppose you are given a fair coin and an unfair.com, which
horrorfan [7]

Answer:

9/25 or 36%

Step-by-step explanation:

The probability of selecting the fair coin is 1/2, and the probability of getting heads with the fair coin is 1/2.

P(fair) = 1/2, P(heads | fair) = 1/2

The probability of selecting the unfair coin is 1/2, and the probability of getting heads with the unfair coin is 2/3.

P(unfair) = 1/2, P(heads | unfair) = 2/3

P(fair and 2 heads) = 1/2 (1/2)²

P(fair and 2 heads) = 1/8

P(2 heads) = 1/2 (1/2)² + 1/2 (2/3)²

P(2 heads) = 1/8 + 2/9

P(2 heads) = 25/72

Therefore, the probability that you selected the fair coin, given that you flipped 2 heads, is:

P(fair | 2 heads) = (1/8) / (25/72)

P(fair | 2 heads) = (1/8) (72/25)

P(fair | 2 heads) = 9/25

What is the measure of ∠XBC?
Angelina_Jolie [31]

Answer:

m∠XBC = 135

Step-by-step explanation:

What is the measure of ∠XBC?

m∠XBC = m∠BAC + m∠BCA

3p – 6 = p + 4 + 84

3p – 6 = p + 88

2p – 6 = 88

2p = 94

From the simplified expression, we need to find the value of p first

From the last line we can see that;

2p =94

Divide both sides by 2:

2p/2 =94/2

p = 47

From the expression, m∠XBC =3p-6

m∠XBC = 3(47)-6

m∠XBC = 141 -6

m∠XBC = 135

Hence the measure of m∠XBC is 135

What is the approximate area of the congruent orange right triangles?
hichkok12 [17]

Answer:

17 in²

Step-by-step explanation:

area is equal to base multiplied to height by 2

base=3.23 in

height=5.12in

area of one triangle = 5.12 * 3.23/2

= 16.536/2

= 8.2688

these triangles are congruent so area of other triangle is also equal to 8.2688

total area= 2*8.2688

= 16.5376

round off

answer =17 in²
