Question

Li throws a 6 -sided biased dice once. The table shows the probability that the dice will land on 1,2,3,5 or 6. Number & 1 & 2 & 3 & 4 & 5 & 6 Probability & 0.15 & 0.1 & 0.05 & & 0.2 & 0.15 Work out the probability that the dice will land on an odd number. (2 marks)

Answer 1

After performing the calculation, we find that the probability of landing on an odd number is \(0.15 + 0.05 + 0.2 = 0.4\).

Answer 2

## Step 1: Identify the odd numbers on the dice. These are 1, 3, and 5. ## Step 2: Refer to the table to find the probabilities of landing on these odd numbers. The probability of landing on 1 is 0.15, on 3 is 0.05, and on 5 is 0.2. ## Step 3: To find the probability of landing on an odd number, add the probabilities of landing on 1, 3, and 5. ### \[P(\text{odd}) = P(1) + P(3) + P(5) = 0.15 + 0.05 + 0.2\]
