If we buy 20 pickles what is the experimental probability of winning 5 or more tickets

Mrac [35]

Answer:

$Pr = 0.66$

Step-by-step explanation:

Given

See attachment for complete question

Required

$P(x \ge 5)$

From the attachment, we have:

$S = 2 + 8 + 4+20+21+19+17+5+2+2$

$S =100$ ---- the sample size

Next, we list out all outcomes more than or equal to 5.

i.e.

$x \ge 5$

5 is represented with the vertical blue rectangle (with frequency 21).

So, the other elements are to the right of frequency 21.

So, we have:

$x \ge 5 = 21+19+17+5+2+2$

$x \ge 5 = 66$

The probability is then calculated as:

$Pr = \frac{x \ge 5}{S}$

This gives

$Pr = \frac{66}{100}$

$Pr = 0.66$

The ratio of boys to girls at the dance was 8 to 4. How many girls were at the dance if there were 88 boys at the dance?

nevsk [136]

88/8=11.

So multiply 4 by 11.

4x11=44

So the ratio is 88:44.

There are 44 girls at the dance
