Probability statistics

So okay, in stats when there is probability that looks like p(fem/type b) it means what is the probability that they are female given they are type b, so it would be where they intersect. Therefore where they intersect on the table is 22 out of the total of 200 people so 1/10. Now that we know that probability let's look at the "or" one, when it says or it means it could be a female or a type b so we would include both totals of each:

97 females+70 type b= 167

now we divide that by the total amount of people so it simplifies down to a probability of 0.835.

Finally, looking at these 2 probability we can see that the "or" probability is far greater than the one previous discussed so it would be the last option if I remeber correctly!!

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

hope this

yes
