1/6 because the only way the sum can be less than 4 if the first die is a 2 is if the second die is a 1.

Answer:the probability that a pensioner catches a flu is 0.3 or \frac{3}{10}

Step-by-step explanation:

<u>Data:</u>

a) Pensioners who have had a flu jab = \frac{3}{5}

b) Pensioners who did not had a flu jab = 1 - \frac{3}{5} = \frac{2}{5}

For the first pair of arrows: a is the probability of the upper arrow and b is the probability of the lower arrow.

<em>If pensioner have had a flu jab, the probability of catching flu is \frac{1}{30}</em>

Data:

c) Catching flu = \frac{1}{30}

d) Not catching flu = 1 - \frac{1}{30} = \frac{29}{30}

The second pair of arrows on the top: Top arrow is c and bottom arrow is d

<em>If pensioner did not have a flu jab, the probability of catching flu is \frac{7}{10}</em>

<u>Data:</u>

e) Catching flu = \frac{7}{10}

f) Not catching flu = 1 - \frac{7}{10} = \frac{3}{10}

The second pair of arrows on the bottom: Top arrow is e and bottom arrow is f.

Q) Probability pensioner catches a flu

P(catches the flu given that he had the flu jab) + P(catches the flu given that he did not have the flu jab)

(\frac{3}{5} x \frac{1}{30}) + (\frac{2}{5} x \frac{7}{10} )

= 0.02 + 0.28

= 0.3

Therefore, the probability that a pensioner catches a flu is 0.3 or \frac{3}{10}

First step, i would try to figure out the slope. think of it as a typical y=mx+b linear equation as you check out the graph.

it's just rise over run (rise up this many, run over that many), and your options are (-2/3) or (-3/2)

start at the y-intercept, which is just above the middle of the graph. if you go down 2 and try to go over 3, you hit the line before you can count 3 units. that means this slope is incorrect.

go back to the y-intercept. down 3, over 2--there you go. your slope here is (-3/2), which immediately gets rid of half your answer choices for having the wrong slope

the next thing you have to do is decide <em>where</em> this graph should be shaded. the shaded region shows the domain; the white region shows what's outside of your domain. this inequality is shaded "below" which means that the y values are LESS than "(-3/2)x +1"

that eliminates another one of your answer choices; choice 3 is correct. the inequality is y < (-3/2)x + 1

if the graphs of inequalities are shaded below and the line is dotted, it's less than. if the graphs of inequalities are shaded above and the line is dotted, it's greater than. general rules for ya

a store selling a couch for $623 on a 24 month payment plan if your down payment of 152 is given and no interest is charged how
sveticcg [70]
First start with $623 and subtract the $152 deposit. Then divide that answer by 24, which equals 19.625. The monthly payment would be 19.63 monthly for 24 months.
