Probability vs Likelihood

This is a workup on Youtube channel StatQuest . Josh Stammer explains the differences between Probability vs likelihood.

mean = 32
sd = 2.5
lb = 32    # lowerlimit
ub = 34     # upper limit
v="grams"
x = seq(-4,4,length=100)*sd + mean
hx = dnorm(x,mean,sd)
plot(x,hx,type="n",xlab=" Values",ylab = "mouse wt",main="",axes=FALSE)
i <-x>=lb & x <= ub
lines(x,hx)

polygon(c(lb,x[i],ub),c(0,hx[i],0),col="red")
area = pnorm(ub,mean,sd) - pnorm(lb,mean,sd)
result = paste("Pr(",lb,"<",v,"<",ub,") = ",signif(area,digits = 3))
mtext(result,3)

axis(1,at=seq(40,160,20),pos=0)
axis(1,at=NULL,pos = 0)

Normally written as pr(weight between 32 and 34 grams | mean = 32 and standard deviation = 2.5)“)

print(result) # probability
print(area*100) # in percentage

Likelyhood means you already have weighed your mouse or mice. So there is no range. Just a weight.

So now with a mouse weight of 34 , what is the likelyhood of weighing a 34 gram mouse?
