Answer:

1 1/16.

Step-by-step explanation:

The Lowest Common Denominator of 2 and 16 is 16 so we have:

9/16 + 1/2

= 9/16 + 8/16

= 17/16

= 1 1/16.

Suppose that you randomly draw one card from a standard deck of 52 cards. After writing down which card was drawn, you replace t

KengaRu [80]

Answer:

0.139

Step-by-step explanation:

We are given that

Total number of cards=52

n=18

We have to find the probability of drawing at least 7 spades

Total number of spaded in deck of 52 cards=13

Probability of getting spade= $p=\frac{13}{52}=\frac{1}{4}$

Probability, $P(E)=\frac{favorable\;cases}{total\;number\;of\;cases}$

Probability of getting no spade= $q=1-p=1-\frac{1}{4}=\frac{3}{4}$

By binomial theorem of probability

$P(X=x)=\binom{n}r}p^rq^{n-r}$

P(x $\geq 7)=1-P(x\leq 6)$

The probability of drawing at least 7 spades= $1-\sum_{r=0}^{6}\binom{18}{r}(\frac{3}{4})^{18-r}(\frac{1}{4})^r$

The probability of drawing at least 7 spades=0.139

Which function below has the smallest slope?. A Graph with a line going through -5 on the Y Axis and Postive 2 and a half on the

Allushta [10]

The three equations can be written as 1) y = 2x - 5 ; 2) y = 2x - 3 and ;3) y = 2x + 5. Now, the slope can be found by slop intercept form of linear equation i.e. y = mx+b where m is the slope. From the above equations, we can see that all the the three have the same slope i.e. m = 2.

If you flip a fair coin 4 times, what is the probability that you will get exactly 2 tails

Ilia_Sergeevich [38]

Answer:

<h3>The answer is 3/8 NOT 50%</h3>

Step-by-step explanation:

One way to solve this problem is to figure out how many ways you can get exactly 222 tails, then divide this by the total number of outcomes you could have gotten. Since every outcome has equal probability, this will be the probability that you will get exactly 2 tails.

How many outcomes are there where you get exactly 2 tails? Try thinking of each outcome as a 4-letter word, where the first letter is "H" if the first coin toss was heads and "T" if it was tails, and so on.

So, the number of outcomes with exactly 2 tails is the same as the number of these words which have 2 T's and 2 H's.

How many of these are there? If we treat all the letters as unique, we'll find that there are 4! different arrangements, overcounting 2! times for every time we only switch the T's around, and 2! times for every time we only switch the H's around.

So, there are 4!/2!2! = 6

4!/2!2!= 6 different outcomes where you get exactly 2 tails.

Altogether, there are 2^4 = 16 total possible outcomes.

So, the probability that you will get exactly 2 tails is 6/16 = 3/8
