HEL ME PLSSS DUE IN 10 MINS FOR 20 POINTS There are 4 blue tiles and 6 red tiles with the letter A written on them in a bag. In the same bag, there are 2 red tiles and 8 blue tiles with the letter B written on them. What is the probability that a randomly selected tile has the letter B or is blue? Give your final answer as the nearest whole percent.

3/5

Step-by-step explanation:

Probabilty of blue tiles: 12/20 =3/5

Probability of letter b tiles: 10/20= 1/2

How to get the denominator?

4+6=10

2+8=10

10+10=20

70%

Step-by-step explanation:

Let's list the 4 types of tiles by color and letter:

4 blue tiles with A

6 red tiles with A

2 red tiles with B

8 blue tiles with B

total number of tiles: 4 + 6 + 2 + 8 = 20

Number of tiles that are either blue or have the letter B (lines in bold above) = 14

p(blue or B) = 14/20 = 7/10 = 7/100 = 70%

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
