Total freshman = 58. Number of freshman who prefer cheese toppings= 14. Determined the probability that a freshman prefer cheese

Yakvenalex [24]

Answer:

The probability that a freshman prefer cheese toppings is 0.241

Step-by-step explanation:

Probability of any event E = $\frac{\textrm{Number of favorable outcomes}}{\textrm{Total number of outcomes}}$

Here, let E : Event of choosing cheese toppings

So, the number of favorable outcomes = 14

Total number of outcomes = 58

So, $P(E) = \frac{\textrm{Number of students who like cheese toppings}}{\textrm{Total number of students}}$

or, P(E) = $\frac{14}{58} = 0.241379$

So,the probability that a freshman prefer cheese toppings is 0.241379

Rounding of 0.241379 to the <u>nearest thousandth</u>, we get

Here , in 0.241379 thousandth digit is 3, and 3 < 5,

so the value of P(E) = 0.241
