Answer:
2.28% probability that it will weigh less than 900 grams
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

What is the probability that it will weigh less than 900 grams?
This probability is the pvalue of Z when X = 900. So



has a pvalue of 0.0228.
2.28% probability that it will weigh less than 900 grams

Step-by-step explanation:
Here let the number of ride tickets be r, and the number of food tickets be f.
Hence

We first plot the two inequalities on graph as shown in attachment. From the graph we see that the two in-equation meet at (4,12)
Hence we can see that the maximum value of r is 4
