With the question 3, you're saying the variance is equal to the mean, but mean= n×p while variance=n×p×q, so they're different right? Like you said in case the question asked you to find variance, the answer is not going to be that of that of the mean
1 b says, fewer than three in six weeks,. But from the question Mean is 1.5 for 1 month. So first find what the mean will be in 6 weeks Note: if 4 weeks is one month, 6 weeks should be one-and-half month, and 8 weeks will be 2 months and so on. So find mean for 6 weeks and that will be 1.5x1.5=2.25 Now, your new mean is 2.25 use that to find fewer than 3.

Wow thanks, God bless you because I never understood this in class but now I'm good to go 🎉
I am glad it was helpful.
Very helpful
You saved my CW🎉🎉🎉
I am glad it helped
Herr you just saved my CWA
God did.
Recommend the video to others.
You explain well, keep it up
Thank you Sir
Wow that was great. Would love to interact with sir on one one . I am a student at Moi university Nairobi Kenya
Glad it was. Hello, you can email me philos.masterclass@gmail.com
Please the last question no.2
Can you also get 0.061 as an answer or it's exactly 0.0611; if so how do you go about it?
yes, you can write it in 3 decimal places, that is 0.061
I got exactly "0.061" as the answer without changing it to any decimal point
Is that wrong?
@@eltonowusu550 It is not wrong.

"In Poisson Distribution only"
Variance=Mean
And Standard Deviation= square root of variance.
You get it?
Please regarding the last questions; a and b
Is it strictly supposed to be 0.06564 and 0.60934 respectively?
No please, you can approximate them to 4 decimal places or 3 decimal places.
But mostly leave your probability answers in 4 dp okay
Thanks
🙌🏻
Please more than 3 is it the same as at least 3
No please.
More than 3 means that you should take it from 4 upward
But, at least 3 means from 3 itself upward.
Is u the same as lambda
Yes and no. 😂😂
Say it’s used interchangeably. They are both mean. You can decide to use any.
Please I'm having some difficulties in the try test.That's 1b

Now, your new mean is 2.25
use that to find fewer than 3.
