What are dependent events in probability?

4 (a) A box contains 40 identical discs which are either red or white. If the probability of picking a red disc is \( \frac{1}{4} \); Calculate the number of (i) white discs ; (ii) red discs that should be added such that the probability of picking a red disc will be \( \frac{1}{3} \). (b) A salesman bought some plates at N50.00 each. If he sold all of them for N600.00 and made a profit of \( 20 \% \) on the transaction, how many plates did he buy?

If event A has a probability of \( 0.5 \) and event B has a probability of \( 0.3 \), what is the probability that both events occur?
