Each time Caroline goes shopping she decides whether or not to buy fruit.
The probability that she does buy fruit is 0.6.
Independently, she then decides whether or not to buy a CD, with a probability of 0.2 that she does buy a CD.
Work out the probability that she buys fruit or buys a CD or both.

Write a paragraph of 100-120 words in which you explain how you will teach these concepts (gender,language and culture) using βWhoβs Irish by Gish Jen β in a South African classroom.
ball is thrown vertically upwards with an initial velocity of 30 m/s.
Using a time step of 0.02 s up to 6.20 s, write a matlab code to give a plot of the vertical distance versus
time for this ball.

and gravitational acceleration π is here taken as negative.
Then use your code to answer the following questions:
(i) To what maximum height does the ball rise?
(ii) What is the index of time at maximum height?
(iii) How long does it take the ball to ascend to maximum height?
(iv) How long does it take the ball to hit the ground?
(v) What happens to the ball if the sign for gravitational acceleration is taken as positive?
If the amount of cosmic radiation to which a person is exposed while flying by jet across theΒ United States is a random variable having the normal distribution with mean as

a) Between 4.00 mrem to 5.00 mrem,Β
b) At least 5.50 mrem,Β
c) No more than 4.5 mrem.
