A warehouse has 35 cartons of toys. Ten cartons contain Legos, 10 cartons contain Encanto toys, 10 cartons contain Squishmallows, and 5 cartons contain miscellaneous toys. John concludes that if he picks a carton at random that he has an equal chance that he would choose Legos and Squishmallows. Is his conclusion correct?
Yes, because there are two possible choices
Yes, because the probability of choosing either is the same
No, because the probability of choosing either is closer to 1
No, because the probability of choosing either is closer to 0
Bethany has a bag that contains only blue, yellow, and green marbles. She chooses a marble, records the color, then returns the marble to the bag.
