Answer: 9
Step-by-step explanation:
In probability problems, look out for the word OR and AND.
OR means adding the probability
AND means multiplying the probability
P(a) = P(jack) + P(queen) + P(king) = (4/52) + (4/52) + (4/52) = 12/52 = 3/13
P(b) = [P(9) + P(10) + P(jack)] × P(red) = [(4/52) + (4/52) + (4/52)] × (26/52)
P(b) = (12/52) × (26/52) = 3/26
P(c) = 13/52 = 1/4
P(d) = P(a diamond) + P(a heart) + P(a spade) = (13/52) + (13/52) + (13/52) = 3/4

Answer:
- there is no M in the diagram
- 145°
- 325°
- 104°
Step-by-step explanation:
EG and IF are assumed to be diameters of the circle. The measures of the two arcs created by a diameter are 180°.
1. There is no M
__
2. arc EF = arc EG -arc FG = 180° -35°
arc EF = 145°
__
3. Angle EDI is a vertical angle to angle FDG, so has the same measure: 35°. Long arc EGI will be 360° minus the measure arc EI
arc EGI = 360° -arc EI = 360° -35°
arc EGI = 325°
__
4. Arc Gi is double the measure of arc GH, so is 38°×2 = 76°. Arc EI is the supplement to this:
arc EI = 180° -arc GI = 180° -76°
arc EI = 104°
