So here, first of all, we need to find the p cap, which is several votes 4 .08 divided by 2 number of 4 .65.
00:57
And then 1 minus p cap will be equal to 1 minus value of p.
01:07
1 .08 divided by 8 65 and this will be equal to so 575 865 this is the event happening and here we have 96 and now let's be the interval let's take the interval interval as it will be as a comma so here a will be equal to 408 divided by 865 minus 1 .96 multiplied multiplied by 25 minus 1 .96 multiplied 5 squared in 408 by 865 multiplied by 408 multiplied by 45 multiplied by 457 by 865 and now we have divided by and this divided by 865 again so the value of a will be 0 point 4384.

This is the value for b.
02:58
And now, value for b, let's find the value of b, that will be 408 divided by 865, added by, added by 1 .96 multiplied by again, the square root, value will be 408 divided by 865, multiplied by 457 by 865 by 865.
