I'm re-posting corrections originally from Wednesday in addition to new ones. Still not sure how to answer #4.

Question

2. Edwin rolls a number cube and then spins a color from a color card (red, yellow, blue, green, white). What is the probability that he will roll an even number and choose a red color?

Ans: P(even)*P(red)
= (1/2)*(1/5)
= 1/10 = 10%

3. A bag contains 5 blue marbles and 3 green marbles. What is the probability of drawing a blue marble followed by a green marble, with replacing the first marble before drawing the second marble?

Ans: P(blue)*P(green)
= (5/8)*(3/8)
= 15/64
= 23%

4. Edwin tossed a number cube several times. He got number '3' on 4 of the tosses. Based on theoretical probabilities, what is the best estimate of the total number of times he tossed the cube?
Ans: 3/(1/6) = 18 tosses?

new questions:
13. Make a list to show all of the possible outcomes when rolling a number cube and spinning a spinner with 4 sections red, yellow, green, blue.
Ans: 24 possible outcomes
#1 - red
#1 - yellow
#1 - green
#1 - blue

#2 - red
#2 - yellow
#2 - green
#2 - blue

#3 - red
#3 - yellow
#3 - green

#4 - red
#4 - yellow
#4 - green
#4 - blue

#5 - red
#5 - yellow
#5 - green
#5 - blue

#6 - red
#6 - yellow
#6 - green
#6 - blue

15. Explain how you could simulate randomnly choosing an odd number from 1-6.
Ans: not sure understand 'simulate'. Does this mean randomly picking a number from a hat?

Answer 1

1-3 are correct

#4. you should have divided 4 by 1/6 to get 24
"3" was the event, it happened 4 times, so 4 is the important number

last one , I did not check the actual entries, but there are 24 of them

Answer 2

Thank you!!
