Answer: P(blue)=1/5. P(yellow)=2/5.
Step-by-step explanation: First find the total number of marbles. 4+1+2+3=10. To find the probability of blue marbles, use this equation (number of blue marbles (2) / total number of marbles(10) ). <em>2/10=1/5</em>.
To find the probability of yellow marbles do this equation (number of yellow marbles (4) / total number of marbles (10) ). <em>4/10=2/5</em>.

Answer:
9 tickets
Step-by-step explanation:
Let x = the number of tickets
let y = the total she spends
So y = 5 + 8 + 0.75x
If the max she can spend is 20, set y = 20 and solve for x:
5 + 8 + 0.75x = 20
13 + 0.75x = 20
0.75x = 20 - 13
0.75x = 7
x = 7 ÷ 0.75 = 9.333333333
Therefore, the max number of tickets that can be bough is 9
