Answer:
The probability of select randomly a red or a blue marble is
Step-by-step explanation:
The probability of an event is the ratio of the number of ways it can happen, to the total number of possible cases.
Select randomly a red or a blue marble are mutually exclusive events because they cannot occur at the same time. When two events, A and B, are mutually exclusive, the probability that A or B will occur is the sum of the probability of each event.
We know from the information given that
- There are 46 red marbles, 59 white marbles and 49 blue marbles
We can use this information to calculate the probability of select randomly a red marble and also the probability to select randomly a blue marble
Now we can calculate the probability that we select a red or a blue marble
Answer:
×=4 is the answer I got hope it's help
The unit rate is going to be calories per serving....calories / serving
Food A :
150 / (3/4) =
150 * 4/3 =
600/3 =
200 calories per serving
Food B :
250 / (2/3) =
250 * 3/2 =
750/2 =
375 calories per serving
Therefore, Food A has fewer calories per serving <==
