I'm sorry hun, i suck at math. If i knew how i would help you. Have you tried looking it up?
Answer:
30/1000
Step-by-step explanation:
red has a chance of 3/10
purple has a chance of 2/10
yellow has a chance of 5/10
for probability, multiply the denominators together, and the numerators together
3*2*5 = 30
10*10*10 = 1000
So the probability of picking red, then purple, and then yellow with replacement is 30 of 1000
Hope this helps!
the probability of getting tails up is 30/50 or most likely
the probability of getting a blue marble is 18/5 or least likely
It can be written as 1.0625
149 will be rounded to 150 so 150×5= 750
