In a class of 160 students, 90 are taking math, 78 are taking science, and 62 are taking both math and science. What is the probability of randomly choosing a student who is taking only math? 56%

39%

49%

74%

HURRY PLEASE

56%

Step-by-step explanation:

Your question is asking for students who are taking only math. Of 160 students, 90 are taking only math. This gives you the proportion of = 0.56. To find percents, just multiply it by 100 to get 56%.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
