P(X≤3) <my choice
P(3≤X≤5)
To determine which probabilities are equal to 0.3, we need to look at the graph. However, since there is no graph provided, we cannot directly identify the probabilities. Nonetheless, I can explain how you can interpret a graph to determine the probabilities.
A probability distribution graph shows the probability of each possible outcome of a random variable. The area under the graph represents the probability. To find the probabilities, you need to look at the intervals or specific values on the x-axis.
In this case, we have four options:
1. P(X≥3): This represents the probability that the random variable X is greater than or equal to 3. To find this probability, you would need to find the area under the graph from 3 onwards. If the graph is a continuous distribution, you would look for the shaded area to the right of 3. If the graph consists of bars (a discrete distribution), you would need to add up the heights of the bars from 3 onwards. Based on your choice, you believe this probability is equal to 0.3.
2. P(5≤X≤8): This represents the probability that the random variable X falls between 5 and 8 (including 5 and 8). To find this probability, you would need to find the area under the graph between 5 and 8. If the graph is continuous, you would look for the shaded area between 5 and 8. If the graph has bars, you would need to add up the heights of the bars between 5 and 8.
3. P(X≤3): This represents the probability that the random variable X is less than or equal to 3. To find this probability, you would need to find the area under the graph up to 3. If the graph is continuous, you would look for the shaded area to the left of 3. If the graph has bars, you would need to add up the heights of the bars up to 3. Based on your choice, you believe this probability is equal to 0.3.
4. P(3≤X≤5): This represents the probability that the random variable X falls between 3 and 5 (including 3 and 5). To find this probability, you would need to find the area under the graph between 3 and 5. If the graph is continuous, you would look for the shaded area between 3 and 5. If the graph has bars, you would need to add up the heights of the bars between 3 and 5.
Without the specific graph, it is not possible to determine which probabilities are equal to 0.3. Please consult the graph or provide more information to accurately identify the probabilities.
