What is the probability of the complement of rolling a number less than 5 by using a six-sided die?
Inessa05 [86]
<h3><u>Answer:</u></h3>

Hence, the probability of the complement of rolling a number less than 5 by using a six-sided die is:

1/3

<h3><u>Step-by-step explanation:</u></h3>

Let A denote the event of rolling a number less than 5 in a six-sided die.

Now, we know that the Total outcomes are: 6

since, the sample space is given as: {1,2,3,4,5,6}

Also Number of favorable outcomes are: 4

since the numbers which are less than 5 are {1,2,3,4}

Now we have to find:

P(A^c)

where P denotes the probability of an event and A^c denote the complement of event A.

We know that:

P(A^c)=1-P(A)

Now,

P(A)=\dfrac{4}{6}\\\\P(A)=\dfrac{2}{3}

Hence,

P(A^c)=1-\dfrac{2}{3}\\\\P(A^c)=\dfrac{3-2}{3}\\\\P(A^c)=\dfrac{1}{3}

Hence, the probability of the complement of rolling a number less than 5 by using a six-sided die is:

1/3

Last year Tammy had $4,500 to invest in two savings accounts. One account earns 7% simple annual interest, and the other account
Nat2105 [25]
Let x be the amount invested at 7% and y the amount invested at 6%

We know that the yearly interest earned = 0.07(x) and 0.06(y)
x+y =4500 
0.07x +0.06 y =290
Solving the equations will give , x = $2,000 and y=$2,500
