i bought a vegetable seed pocket containing 20 seeds. A manufacturer label on the pocket said that the seeds have at least 90% germination rate. I planted all 20 seeds following their instructions in preparing soil and water. They told me if an "unlikely event" happens, return the packet. Any event which is less than 5% chance of happening is considered an unlikely event. Should i consider less than or equal to 17 germinating an "unlikely event"? The answer is no. Why?P

i bought a vegetable seed pocket containing 20 seeds. A manufacturer label on the pocket said that the seeds have at least 90% germination rate. I planted all 20 seeds following their instructions in preparing soil and water. They told me if an "unlikely event" happens, return the packet. Any event which is less than 5% chance of happening is considered an unlikely event. Should i consider less than or equal to 17 germinating an "unlikely event"? The answer is no. Why?P

*please tell me why the answer is no

Answer 1

To determine whether less than or equal to 17 germinating seeds is considered an "unlikely event," we need to compare it to the given definition of an "unlikely event." According to the manufacturer label, any event with a probability of less than 5% is considered unlikely.

In this case, we have a packet of seeds with a stated 90% germination rate. This means that out of the 20 seeds, we can expect around 18 seeds to germinate on average (90% of 20).

If the germination rate is as expected, and 18 seeds germinate, this result falls within the likely range and is not considered an "unlikely event" according to the given 5% threshold.

Therefore, less than or equal to 17 seeds germinating is not classified as an "unlikely event" since it is not below the 5% probability threshold.
