The contingency table below gives the counts of students by activities and gender. Band Sports Debate Total Male 105 320 7 432 F
Ber [7]

Answer:

599/711

Step-by-step explanation:

           Band Sports Debate Total

Male     105 320  7         432

Female 105 160         14         279

Total 210 480          21          711


P(female or plays sports)

We want the probability that they are female or play sports, but we cannot double count the female sports players, so we subtract them

 P(female) + P (sports) - (female and sports)

female/total + sports/total - female sports/ total

279/711 + 480/711 - 160/711

599/711

8. Jenny is getting dressed for school,
UkoKoshka [18]

Answer:

\huge\boxed{\bf\: Probability = \frac{4}{9}}

Step-by-step explanation:

According to the given information,

  • Pairs of black pants = 2
  • Pair of brown pants = 1
  • Pairs of blue pants = 2

Then, total pairs of pants = 2 + 1 + 2 = 5

Similarly,

  • Pink T-shirts = 2
  • Blue T-shirts = 2

Then, total number of T-shirts = 4

This gives us the total nunber of clothing articles with Jenny, i.e.,

Total pairs of pants + Total number of T-shirts

= 5 + 4

= 9

Now, the probability of pulling out a pair of black pants & a blue T-shirt will be:

Total pairs of black pants + Total nunber of blue T-shirts/Total clothing articles

= 2 + 2 / 9

= 4/9

\rule{150}{2}
