The probability of a sporting event being cancelled due to rain or lightning is 6/25

<h3>What is Probability?</h3>

This is the likelihood or chance that an event will occur.

Probability = Expected/Total

Given the following

Pr(rain) = 3/5
Pr (lightening) = 2/5

The probability of a sporting event being canceled due to rain or lightning = 3/5 * 2/5

The probability of a sporting event being canceled due to rain or lightning = 6/25

Hence the probability of a sporting event being cancelled due to rain or lightning is 6/25

A cinama has 3 screens on last saturday the was 500 visitors 40% went to screen 1 25% went to screen 2 and the rest to screen 3

olga nikolaevna [1]

Answer:

The answer to your question is 200 visitors went to screen 1

125 visitors went to screen 2

175 visitors went to screen 3

Step-by-step explanation:

Data

3 screens

total number of visitors = 500

40% screen 1

25% screen 2

rest screen 3

Process

1.- Calculate the 40% of 500

500 visitors ------------------- 100%

x ------------------- 40%

x = (40 x 500) / 100

x = 20000/100

x = 200 visitors

2.- Calculate the 25% of 500

500 visitors ------------------- 100%

x ------------------- 25%

x = (25 x 500) / 100

x = 12500/100

x = 125

3.- Calculate the number of visitors to screen 3

500 - 200 - 125

175

Yvonne deposits $5000 in a bank account which pays 4% per annum compound interest. What is the total interest earned in 5 years,

Marianna [84]

Answer:

<h2>$1,083</h2>

Step-by-step explanation:

The compound interest formula is expressed as $A = P(1+r/n)^{nt}$

A is the total amount after n years

P is the amount deposited (principal)

r is the rate (in %)

t is the time (in years)

n is the time of compounding

Given P = $5000, r = 4% = 0.04, t = 5 years, n = 1 year (per annum compound interest)

On substituting into the formula we have;

$A = 5000(1+0.04)^{1(5)} \\A = 5000(1.04)^{5} \\A = 5000*1.2166529\\A = 6,083.26$

Interest earned = Amount - Principal

Interest earned = $6,083.26 - $5,000

Interest earned = $1,083.26 ≈ $1,083

Hence, the total interest earned in 5 years is $1,083 to the nearest dollars.
