Need to divide both sides of the equations by -4 and it’s going to give you this m+6=2. Then move the constant to the right-hand side and change its sign and it’s going to give you this m=2-6. And then calculate the difference and then it’s going to give you this m=-4.

It is known that 10% of the calculators shipped from a particular factory are defective. what is the probability that at least o

seraphim [82]

P = 10% = 0.1
q = 1 - 0.1 = 0.9
P(at least one defective calculator) = P(1) + P(2) + P(3) + P(4) = 1 - P(0)

The brobability of a binomial distribution is given by
$P(x)=^nC_xp^xq^{n-x}$
where: n = 4
$P(0)=^4C_0(0.1)^0(0.9)^4=1\times1\times0.6561=0.6561$
Therefore,
P(at least one defective calculator) = 1 - 0.6561 = 0.3439
