Answer:
D. {R, G, Y, B}
Step-by-step explanation:
Number of balls = 4
red ball (R) = 1,
green ball (G) = 1,
yellow ball (Y) = 1,
blue ball (B) = 1
therefore the Pr (choosing a ball) = 1/4
but the sample space (the possibilities of either choosing any color of the balls) will be {R, G, Y, B}
Y/4-3. When y=20, it will equal 2. 20/4 is 5, minus 3 is 2.
Answer:
$3 and $2
Step-by-step explanation:
let p represent popcorn and d drinks , then
2p + 3d = 12 → (1)
3p + 5d = 19 → (2)
multiplying (1) by 3 and (2) by - 2 and adding will eliminate p
6p + 9d = 36 → (3)
- 6p - 10d = - 38 → (4)
add (3) and (4) term by term to eliminate p
0 - d = - 2
- d = - 2 ( multiply both sides by - 1 )
d = 2
substitute d = 2 into either of the 2 equations and solve for p
substituting into (1)
2p + 3(2) = 12
2p + 6 = 12 ( subtract 6 from both sides )
2p = 6 ( divide both sides by 2 )
p = 3
Popcorn costs $3 and a drink costs $2
