Assume that 60% of people are left-handed. if we select 5 people at random, find the probability of each outcome described below, rounded to four decimal places: a. there are some lefties ( ≥ 1) among the 5 people. 9898 b. there are exactly 3 lefties in the group. 2304 c. there are at least 4 lefties in the group. d. there are no more than 2 lefties in the group. e. how many lefties do you expect? f. with what standard deviation?

step-by-step explanation:

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°
