The number of emails (X) received in an hour by a certain company is a Poisson random variable with parameter 1 = 1.5. Calculate the probability that probability that (i) Two or more emails are received in an hour. (2 marks) (ii) Exactly four emails are received in an 3 hours, (2 marks)​

the answer is a

step-by-step explanation:

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:
