Step-by-step explanation:
medals?
Decide if the situation involves a permutation or a combination, and then find
the number of ways to award the medals.
Answer: Permutation; number of ways = 120
Step-by-step explanation:
Answer with explanation:
Number of runner= 5
Number of Distinct Medal = 5
First Medal can be Awarded in 5 ways, second Medal can be awarded in 4 ways and third Medal can be awarded in 3 ways , fourth medal can be awarded in 2 ways and fifth Medal can be awarded in one way.
So, total number of ways =5 × 4×3×2×1=120 way
⇒We will use the concept of Permutation as there are five distinct medal and five different runners
So, Five distinct places can be filled in 5! or ways as order of arrangement is Important because any of the five candidates can win first second, third , fourth or fifth Prize.
= 5!=5×4×3×2×1=120 ways
Because, n!=n×(n-1)×(n-2)×........1.
Answer:
THERE YA GO BUDDY!!
Step-by-step explanation:
To work out the probability that both randomly chosen students have only visited Mexico, we need to consider the number of students who have visited Mexico and subtract those who have also visited other countries.
From the given information:
- 11 students have visited Canada
- 2 students have visited Canada and Mexico (but not the USA)
- 3 students have visited Mexico and the USA
- 1 student has visited all three countries
- 6 out of the 19 students who have visited the USA have also visited at least one of the other countries.
We can calculate the number of students who have only visited Mexico as follows:
Total students who have visited Mexico = Total students who have visited Mexico and the USA - Students who have visited all three countries - Students who have visited Canada and Mexico (but not the USA)
= 3 - 1 - 2
= 0
Since there are no students who have only visited Mexico, the probability that both randomly chosen students have only visited Mexico is 0.
