Answer:

i) 90/150[3/5] ii) 60/150[2/3]

Step-by-step explanation:

SEE PROBABILITY = FAVOURABLE OUTCOMES / TOTAL OUTCOMES

HERE IN i) FAVOURABLE OUTCOME IS 90 BECAUSE WE WANT THE PROBABILITY OF CORRECT FORECASTS

SIMILARLY IN ii) OUR FAVOURABLE OUTCOMES ARE 150-90=60

AND TOTAL OUTCOMES IS 150

HENCE BY USING ABOVE FORMULA WE CAN FIND THE PROBABILITY

(DO NOT FORGET TO REDUCE IT INTO LOWEST TERMS)

HOPE THIS HELPS YOU :)
