$P(X=x)= nC_xp^x(1-p)^{n-x}$ Number of Senators be n=5
Probability that the Senators will strongly support the tax proposal be $p=\frac{25}{100}=0.25$
Let X be the number of Senators will strongly support the tax proposal.
Using Binomial Distribution,
$P(X=x)=nC_xP^x(1-p)^{n-x}$
Now Plug in the values of n and p,
$P(X=x)=nC_xp^x(1-)^{n-x} [\tex] To find the probability that 3 out of the 5 Senators will support the tax proposal is [tex] P(X= 3)=5C_3(0.25)^3(1-0.25)^{5-3}\\ =0.08789$

A cruise ship travels from Port Cassett North at speed of 34 km/h for 2.5 hours. Then it turns 90° and travels west at 30 km/h f

IrinaK [193]

34km/h*2.5 hours=85km
30km/h*7.3 hours=219km
This makes a right triangle, so you plug it into the Pythagorean Theorem. The result is 234.92km from Port Cassett.
