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

5 biscuits cost 30p altogether how much do 7 biscuits cost?
andrezito [222]
First we want to find how much an individual biscuit costs. 
If 5 biscuits costs 30p, then  
5 x 1 biscuit = 30p 
divide both sides by 5
1 biscuit = 6p 

If one biscuit costs 6p, and we want to know how much 7 biscuits cost, then:

7 x  6p =42p

7 biscuits costs 42 p
