[2] (c) Another bag contains 15 red beads and 10 yellow beads. Ariana picks a bead at random, records its colour and replaces it
in the bag. She then picks another bead at random. (1) Find the probability that she picks two red beads. [2] (ii) Find the probability that she does not pick two red beads. (0)
The probability of spinning red is , the probability of spinning a 1 is , the probability of spinning an odd number is , and the probability of spinning a 9 is 0.
Step-by-step explanation:
Since there are a total of 6 possible outcomes, you can use this in the following questions. There are 2 red tiles, so the probability of spinning red is or . Since there are only one 1 tile, the probability of spinning a 1 is . Since there are three odd numbers, the probability of spinning an odd number is . Since there are no 9 in the spinner, the probability of spinning a 9 is 0 or never.
