In a box 25 cards are there and 1 to 25 numbers are written on them. one card is drawn randomly. what is the probability that it
tensa zangetsu [6.8K]

<u>Explanation </u><u>:</u>

<u>Given that:</u>

  • In a box 25 cards are there and 1 to 25 numbers are written on them.

  • • One card is drawn randomly.

<u>To Find:</u>

  • • What is the probability that it is multiple of 5.

<u>We know that:</u>

P(E)= F/T

<u>Where,</u>

P(E)= Probability of an event

• F= Favourable outcomes . T = Total outcomes

<u>We have:</u>

F = Number of cards which are multiple of 5

Cards having the number 5, 10, 15, 20, 25 are the multiples of 5.

So, F = 5

T = Total number of cards

• T = 25

P(F) The probabilityP(E) = The probability that it is multiple of 5

Finding the probability that it is multiple of 5:

  • P(E)= 5/25

  • P(E)=1/5

<u>Hence,</u>

The probability that it is multiple of 5 is ⅕

After an importer paid 30% of the cost of an item in taxes and $65.00 for freight charges, the total bill was $520.00. The cost
Marianna [84]

Step-by-step explanation:

let the cost of the item be y

for taxes

30%of y

30/100×y=3y/10

=0.3y

freight charges =65

total =520

0.3y+65=520

0.3y=520-65

0.3y=455

y=455/0.3

y=$1516.7

y≈$1517

If X = 13 units, Y = 15 units, and h = 11 units, what is the area of the parallelogram shown above?
Sedbober [7]

Answer:

the area of the parallelogram = base times the height

For the given parallelogram :

x = 8 units, y = 13 units, and h = 11 units

1) If x is the perpendicular to h

So, the base = 8 and the height = 11

So, the area = 8 * 11 = 88 square units

2) If y is the perpendicular to h

So, the base = 13 and the height = 11

So, the area = 13 * 11 = 143 square units
