Answer:
A) The relative frequencies in the table are reasonably close; C) The relative frequency of rolling an even number is 0.51.
Step-by-step explanation:
The relative frequencies given are at most 0.02 apart. This means they are reasonably close.
The theoretical probability for each outcome would be 1/4, or 0.25; this means the theoretical probability of rolling an even number would be 0.50, not 0.51.
However, the relative frequency of rolling an even number would be 0.24+0.27 = 0.51.
Since the relative frequencies are reasonably close, the number cube is likely to be fair.
The gcf of 15 and 10 is 5
Probability=number of specific outcomes/total possible outcomes
And the probability of two events happening at the same time is P(1)*P(2), or the product of the probabilities of each event...
In this case:
P(primary color)=3/6=1/2
P(head)=1/2
P(primary and head)=(1/2)(1/2)=1/4
Answer:
6.
Step-by-step explanation:
Lucy studies one less (-1) than twice the number of hours a week that rose studies (2 * R), lucy studies 11 hours a week. What we do is add 1 hour to lucy's 11, to get 12, then divide by 2 as lucy studies twice the hours. 12 / 2 = 6.
