Answer:
probability of selecting a student who plays a sport but does not watch rugby out of the people who play a sport.
Step-by-step explanation:
"Find the probability that a student chosen at random from those who play a sport does not watch rugby."
90-15= 75 students either play a sport OR watch rugby
65+71-75=
136-75=
61 people play a sport AND watches rugby
14 people play a sport and DOES NOT watch rugby
is the probability of selecting a student who plays a sport but does not watch rugby out of the people who play a sport.
A= 3400t + 600 | given formula
21000= 3400t + 600 | substitute the altitude into the formula
20400 = 3400 | subtract 600 from both sides
6 = t | divide both sides by 3400
6 minutes
1) 100% - 30% = 70% - remainder
70% = 0,7
50% = 0,5
2) 0,5 * 0,7 = 0,35 = 35% - made some pancakes
3) 70% - 35% = 35% = 0,35 (= 1400 g)
4) 1400 : 0,35 = 4000 g = 4 kg - aswer.
