1 answer:
we are going to create a table in excel and we will assign different values of topping to know when the price is equal in both pizzerias

5 toppings from palanzio’s pizzeria
6 toppings from guido’s pizza
cost palanzio’s pizzeria----> 6.80+0.90*5-----> $11.30

Answer:
The correct answer is 0.05882.
Step-by-step explanation:
A deck of cards have 52 cards, 13 cards of each suit.
We are drawing two cards without replacement.
We need to find the probability of getting a diamond as the first card.
Favorable outcomes are 13 and total number of outcomes are 52.
Thus this probability is .
Now for the next draw we again want to pick a diamond card.
Favorable outcomes are 12 and total number of leftover cards are 51.
Thus this probability is .
Now the probability that both cards are diamonds is ×
=
= 0.0588235 ≈ 0.05882
