jay beats terry at table tennis 3 out of 5 games. what is the experimental probability that terry will win their next game
lozanna [386]

Answer:

The experimental probability that terry will win their next game is \frac{2}{5}

Step-by-step explanation:

While theoretical probability is the ratio of the number of favourable outcomes to the total number of outcomes, the experimental probability is the ratio of number of times the event is occurring to the total number of trials of the experiment.

Out of 5 games jay wins  3

Now the experimental  probability that terry will win their next game

 = 1 - Probability of Jay winning the game----------------------(1)

Probability of Jay winning the game = \frac{\text{number of occurrences of the event}}{\text{total number of trials made}}

=> \frac{3}{5}----------------------------------------------------(2)

Substituting (2) in (1)

=> 1 -  \frac{3}{5}

=>  \frac{5-3}{5}

=>  \frac{2}{5}

I need help on this...how do i do it
Ugo [173]

Answer:

<h2><u><em>D</em></u></h2>

Step-by-step explanation:

You can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 549 and 999. I know that

61/111

is the same as

61÷111

Then using

Long Division for 61 divided by 111

and rounding to a Max of 4 Decimal Places gives me

=0.5495/.5495

<h3>then move the decimal point a digit to the <u><em>RIGHT!!!!</em></u></h3>

You give up a full-time salary of $45,000 a year to go to school for 2 years. The total cost of going to school is $30,000. If y
Sloan [31]
I say that answer would be C:

2 years of lost wages 
(45K+45K) = 90K 
TOTAL cost of school = 30K 

sum of investment 
(90K+30K) = 120K 

5 years to recover investment 
(120K/5yrs) = 24K per year 

Salary plus amount required to recover investment 
<span>(24K+45K) = 69K


I hope my answer has come to your help. God bless and have a nice day ahead!</span>

What is the product in simplest form? State any restrictions on the variable. Please show your work.
mote1985 [20]
You have the following expressions given in the problem above:

 (y^2/y-3)(y^2-y-6/y^2+y)
 
 By applying the exponents properties, you can simplify it, as it shown below:

 (y^2/y-3)(y^2-y-6/y^2+y)
 (y^4-y^3-6y^2)/(y^3+y^2-3y2-3y)
 (y^4-y^3-6y^2)/(y^3-2y2-3y)

 Then, you have:
 y^2(y^2-y-6)/y(y^2-2y-3)
 (y^2-y-6)/(y^2-2y-3)

 The answer is: (y^2-y-6)/(y^2-2y-3)

The table below shows all the possible outcomes when Henry spins two fair spinners. Spinner A is labelled with sections D, M and
aleksandr82 [10.1K]

Step-by-step explanation:

a)

well, logically, it must be M, 2

b)

this is a combined probability for one single pair of possible outcomes.

there are 15 pairs, all with the same probability.

so, P(Q, 4) = number of desired outcomes / number of possible outcomes = 1/15

as combined probability we can also say the probability to get 4 on one wheel is 1/5, and the probabilty to get Q on the other wheel is 1/3

so, P(Q, 4) = 1/3 × 1/5 = 1/15
