A student identification card consists
denis23 [38]

Answer:

\frac{1}{30240}

Step-by-step explanation:

Given

ID Card of 5 digits

Possibly Digits = {0,1...,9}

Required

Probability that a card has exact number 94213

First, we have o determine the total possible number of ID card numbers

Let the card number be represented by ABCDE

Given that repetition of digits is not allowed;

<em>A can be any of 10 digits</em>

<em>B can any of the remaining 9 digits</em>

<em>C can be any of the remaining 8 digits</em>

<em>D can be any of the remaining 7 digits</em>

<em>E can be any of the remaining 6 digits</em>

<em />

Total number of cards = 10 * 9 *8 * 7 * 6

Total = 30240

Provided that the card number is generated at random; each card number has the same probability of \frac{1}{30240}

Hence, the probability of having 94213 is \frac{1}{30240}

What's 2/4 x 1/3? And pls provide work on how u got the answer.
igomit [66]
Just multiply the top number by the top number and the bottom numbers by the bottom numbers so


2/4 times 1/3=(2 times 1)/(4 times 3)=2/12

so to simplify, we find the ones exg 4/8=1/2 because 1/2 times 4/4=4/8 and 4/4 cancels out so

2/12=2/2 times 1/6
=1/6

You didn't specify how big the festival is. so i can't find the answer.....but i will try
first let's devide 10,000 by 0.9 to see how many square metres we need, to fit 10,000 people
10,000÷0.9=11,111 square meters
we need atleast 11,111 meters of land for a safe festival
